Seldom does anyone examine the reasoning behind wanting to have children.
Among the explanations given by social scientists:

Most girls have extensive experience playing family games - house, dolls, mommy. In our society girls are more likely to have been socialized in some ill conceived way to be mothers, while boys tend to run away from playing house. And although boys are generally still thought of as one day becoming wage earners, society really doesn't help them realize these values through play.
Every college graduate should be fairly familiar with Abraham Maslow's theory of self-actualization. Briefly, he asserts that before a person can care and nurture another, he or she must have experienced being loved and cared for, preferably since very early childhood. A person who is kept fed, sheltered, clothed, safe and secure is a good candidate for personhood, and can then further develop friendships, love for others, and high efficacy. Only those who achieve selfhood to this point have all the background experience to be good parents.
Further, there are some developmental tasks for prospective parents (couples!):
Once a consortium of interested folk (psychologists, law makers, pediatricians,
and so on) met in Washington D.C. to define the ideal state of existence
for children worldwide. The result of their meeting was A Bill of Rights
for Children from the Joint Commission on Mental Health
of Children (1970)
They determined that all children have:
Sadly, U.S. parents are in a position to rear good citizens, yet they tend to violate the simplest rules of parental conduct. For an experiment, go to a place of commerce where children are supposed to be welcome (an amusement park, the grocery store, etc.) and listen for crying kids and crabbing parents.
Psychological Conditions Fostering Healthy Child Development
Parental Rejection is rampant, such as physical neglect, denial of affection, lack of interest in child's activities, harsh or inconsistent punishment, lack of respect for the child's rights and feelings. The effects on children are obvious to most who think:
Children need to be supplied with an calm, orderly lifestyle to rely upon so that cogent cognitive development can ensure. A clearly structured environment is:
Proper guidance used effectively requires knowledge of human development - and love.
Ineffective Parenting Conditions - here's the rub!
Creating a stimulating and responsive environment doesn't require enormous expenditures of money - but it does take lots of time - times spent touching, tasting, listening, looking teaching, exploring. Children must be constantly be motivated to move out of old patterns of behavior and desire and into new ones. For parents who can't afford paper for drawing, there's ton's of it thrown away everyday by businesses - and it is blank on one side. When I was a kid, I was always looking at the ground as I walked along - people thought I was depressed. What I was doing was emulating my father who taught me to use what I could find.
Signs that Pregnancy has occurred:
Pregnancy by Trimesters
1st trimester is difficult for the mother - Nausea, vomiting, fatigue, dizziness, headaches, depression, irritability and anxiety. Heightened emotionality. Husbands may deal with these changes in a number of ways. They may refuse to accommodate these behaviors, or they may act in an informed manner, trying to understand.
It is important that women are careful regarding the use of anti-nausea drugs - all drugs in fact. An understanding g husband can largely replace dependence on these things - in fact . . . there is much less use and more informed use since daddies have been going to prepared childbirth classes.
Prenatal care suggests that pregnant women stay away from smoking (low birth weight, premature infants, and infants prone to s.i.d.s., and leads to infants who are unresistant to disease), and alcohol of any kind (fetal alcohol syndrome). Women should take their vitamins, get exercise and eat healthy, balanced foods.
2nd trimester - most of the physiological nasties go away, replaced by a 'pleasant' feeling for the mother. Quickening excites both. Husbands frequently lie with an ear on mother's abdomen, and even invite close friends or complete strangers for a listen or feel. Father's seem to enjoy this more than mothers - However . . .
3rd trimester - more discomfort, not physiological, but physical - momma is getting big in the middle. Because baby is getting bigger, pressure is applied to mom's internal organs, resulting in indigestion, a feeling of a constant need to urinate, shortness of breath, and a change in her center of gravity. Mother is stressed by the extra weight gain - self-image-wi se - so nicknames like 'Goodyear' or shouts of 'Thar she blows!" are not advised - Worries over the baby's health and development as well.
Couvade - in some primitive societies, men exhibit all the signs of the pregnant wife, screaming in agony over simulated labor pains, crying for comforts. Men will dress in wife's clothing, disguise straw dolls as infants and hide them under their clothes. These babies will be "delivered" in the same manner as the real baby and simultaneously.
The social function of couvade is to publicly establish paternity. Spiritually, the function is to confuse evil spirits lurking to enter the real child by waving the doll instead.
Prepared Childbirth Classes - Lamaze is pretty popular and will suffice.

When baby comes home from the hospital, the realistic expectations of
parents are realized.
Our society, through social expectations, burdens mothers with most
of the developmental and nurturant duties of child rearing.
Fathers traditionally are expected to:
Effective parenting for infants through school age:
Discipline: Diana Baumrind (1979) offers a typology of parental styles with research that documents the typical child from each type of parenting style.

Authoritarian parents insist on obedience requiring children to assume responsibility without respecting kids personal worth, privacy, or other human rights. There is the expectation of responsible behavior without the promise of increased privilege.
Permissive parents insist on complete freedom for children and their enjoyment of all privileges without the expectation of responsible behavior. Neglectful parents are included as permissive.
Authoritative parents exert control and discipline gradually and developmentally. Limits are set to be broken as the child grows into maturity. Controls are placed as they are needed and relaxed as behavior training occurs. Of the three types of parenting, the resultant child is likely to be shy and withdrawn and prone to aggressive behavior if their parents were authoritarian. These people, while they achieve more in the $$$ sense, are very unsure of themselves and score low on self-esteem tests.
If their parents were permissive, the resultant child will likely grow up hedonistic, easily bored and unexcited by life, and unhappy. More likely to be depressed. Among all children, the ones with authoritative parents were most likely to exhibit healthy expectations for themselves, and were more likely to have higher mental health. These are the healthiest of all children, with regard to parenting received. Permissive parents either never punish in any way, or they are very inconsistent with their issuance of punishments. Authoritarian parents are more likely to have more children, to use corporeal punishment.
Now - authoritative parenting takes four times as much energy and time, but the result is a child that is better prepared to face the enormous peer pressures of adolescents and young adulthood. These children are more self-assured and independent at earlier ages than children parented using other styles.
Which would you rather have in the long run - a child that is easily lead and influenced as a child and an adult - or a difficult strong willed child with the necessary information to make his or her own decisions.
Ways to use discipline in non-threatening (and therefore, healthy) ways:
Parents of adolescents report lower levels of life satisfaction, less marital happiness, and more general distress than parents of younger children, or the childless.
Spite, revenge, passive aggressiveness, and rebelliousness toward parents are all normal, even healthy, aspects of adolescence. However, among families whose kids were seeing psychologists, feelings of closeness with siblings, and often a sublayer of harmony were the norm.
Current research shows that all bickering and arguments seldom undo close emotional bonds or lead adolescents and their parents to reject each other. In fact, it is precisely the conflict that is the mechanism that drives adolescents out of the house and into independence. If home life was completely satisfying, then children would never leave.
With the onset of puberty occurring a little earlier, the adolescent's need to "desatellize" and establish some autonomy, occurs a little earlier as well. Inconsistent parenting, blocked communication channels, and extremes of strictness (or permissiveness) can make a strained situation worse than it needs to be. Parents, because they've been making decision for their children for so long, like to think they have complete power to mold their children's personalities, and intellects. Clearly experiences are crucial and determine a child's basic nature by age six.
The Spockian Challenge
After WWII, a couple of million of ex - G.I.'s cam home and married their sweethearts and moved into a tract house. Dad took a job in a prosperous economy fed by WWII-Korea-Vietnam. Mom could stay home and tend to the house and kids. Suddenly everyone was having babies and the Baby Boom was in full swing. Several parenting books emerged with the diaper services and toy companies, and psychology departments.
Spock's book - listed symptoms of childhood diseases and remedies - and spoke for the first time about Baby's Emotional and Mental Health. (Only women were reading this!). Mom was told she was responsible for Baby's emotional stability. If baby was harshly disciplined, he wouldn't be emotionally responsive as an adult. She was instructed to allow baby to express itself - to think out loud, to be expressive. The highly moralistic 50's also taught baby to trust the government, Parents never lie, respect the truth, and be compassionate to those less fortunate. fight only as a last resort, and that America was the greatest place in the world to live.
As we entered the 1950's, we entered the age of the teenager, and the development of a distinct "youth culture". The Government played into the hands of this scenario by consistently getting involved in wars that they couldn't justify. The Economy also found the opportunity to sell more and more needless products to youngsters, based on the idea that teen love, teen sexiness, teenage bullshit angst, could be mined for profit. These things tended to be used by parents to replace the hands-on parenting for which they have little time, what with the job and all.
Here we are today, and the kids are screwed up (I don't have to remind anyone of the tremendous increases in the depth and breadth of juvenile crime.).
Marriage After Transition to Parenthood
Barclay, K., Benelli, C., & Curtis, A. (1995). Literacy begins at birth: What caregivers can learn from parents of children who read early. Young children, 50(4), 24-28. Characteristics that foster early literacy development in children can be duplicated in child care centers - rich literacy environment, encouragement to early writing, structured activities, and interactive strategies during book sharing.
Belsky, J., Crnic, K., & Gable, S. (1995). The determinants of coparenting in families with toddler boys: Spousal differences and daily hassles. Child Development, 66, 629642. Neither demographic nor child-rearing differences significantly predicted any measure of coparenting. The more spouses differed on personality measures of extroversion and interpersonal affect, the more they were unsupportive with negative emotions. Increased daily hassles and larger personality differences between parents the less likely support for coparenting.
Belsy, J., Spanier, G., & Rovine, M. (1983). Stability and change in marriage across the transition to parenthood. JMF, Aug., 567-557. All said and done, having a baby has a slight negative to no impact on marital relationships for both men and women.
Benaskich, A., Brooks-Gunn, J. & Clewell, B. (1992). How do mothers benefit form early intervention programs? J. Applied Developmental Psychology. 3, 311-362. A meta-analysis of various intervention programs revealed significant effects on maternal employment and education, fertility, and mother-infant interaction, with 70% of the programs having a significant positive influence on maternal attitudes and knowledge about childrearing in a positive direction.
Brems, C., & Sohl, M. (1995). The role of empathy in parenting strategy choices. Family Relations, 44, 189-194. A child's behavior (good or bad) was the best predictor of parenting strategy choices - participants endorsing fewer rewarding/talking strategies and more negative ones for problem children.
Capaldi, D., Forgathch, M., & Crosby, L. (1994). Affective expression in family problem-solving discussions with adolescent boys. J. Adolescent Research, 9 (1), 28-49. 41-77% of family problem-solving time was taken up by neutral behavior, which appears to have reduced the overall duration of the session. Mothers and boys exhibited contempt for each other longer than did fathers and boys. The boys exhibited long durations of sadness and whining. Stepfathers showed some trend a slightly higher tendency for negative affect compared to biological fathers.
Crockett, L., Eggebeen, D., & Hawkins, A. (1993) Father's presence and young children's behavioral and cognitive adjustment. J. Family Issues, 14, 355-377. In regression analysis, all forms of father presence disappeared in the prediction of behavior and cognitive adjustment of children in favor of family resources, father's income contribution, and mother's IQ and educational attainment.
Forehand, R., & Nousiainen, S. (1993) maternal and paternal parenting: Critical dimensions in adolescent functioning. J. Family Psychology, 7, 231-221. Parenting styles of mothers and fathers were significantly related to each other. Mothers reported using more diverse parenting styles than fathers. An accepting parenting style appears to be the best predictor of school behavior and other aspects of adolescent functioning.
Friese, B., Hooker, K., Kotary, L., Schwagler, J., & Rimmer, M. (1995). Family stories in the early stages of parenthood. JMF, 57, 763-770. 96% of the sample reported talking about their childhood, most often to their children, at least occasionally. Fathers told stories with stronger achievement themes, mothers told stories with stronger themes of affiliation. Parents with preschool children most often told stories with achievement themes.
Giles-Sims, J., Strauss, M., & Sugarman, D. (1995) child, maternal, and family characteristics associated with spanking. Family Relations, 44, 170-176. Spanking was prevalent for 61% of the mothers of preschoolers, 34% of the mothers of 6-9 year olds, and 16% of the mothers with children older than 9. As SES increases, spanking decreases. While more boys than girls are spanked, among children who are spanked the frequency is the same. Older mothers were less likely to spank. The prevalence of spanking among unwed mothers was not higher than that of wed mothers, but the frequency of spanking was higher. Black mothers spank more, Catholic mothers spank less. Among the mothers who spanked preschoolers, their children are spanked an average of 150 times a year (10 times greater than those parents estimate).
Harris, K., & Morgan, S. (1991). Fathers, sons and daughters: Differential paternal involvement in parenting. JMF, 53, 531-544. Greater involvement of fathers with younger children was found. No significant differences in father involvement was found across same gender pairs of children (2 boys, or 2 girls), but mixed gender pairs of siblings resulted in greater father involvement with the boy. Further, men whose wives characterized the marriage as "not satisfying' were less involved with their children. Mother's full-time employment increased father's behavior toward children, but not his affective involvement.
Henwood, P., & Solano, C. (1993). Lonliness in young children and their parents. J. Genetic Psychology, Oct. 35-45. Signif. relationship was found between level of loneliness in a young child and that of the mother.
Langlois, J., Ritter, J., Casey, R., & Swain, D. (1995). Infant attractiveness predicts maternal behaviors and attitudes. Developmental Psychology, 31 (3), 464-472. Mothers of attractive infants engaged in more affectionate interacton with their babies. Mothers of less attractive infants engaged in more routine caregiving. Less attractive infants were perceived as interfering more in their parents lives - with boys seen as interfering more than girls. Attractive 3 month olds were more likely to tough, cling, and hold the caregiver.
Rueter, M., & Conger, R. 91995). Antecedents of parent-adolescent disagreements. JMF, 57, 435-448. A hostile family context correlates positively with disrupted problem solving and family disagreements. Such families grow more and more defensive and disruptive over time. Families bringing positive characteristics into early adolescence are likely to become increasingly warm and supportive, thus lowering the frequency of disagreements over time. Ryder, R. (1973). Longitudinal data relating marriage satisfaction and having a child. JMF, Nov, 604-606. the clearest finding was that women who have a child become more likely to report that their husbands are not paying enough attention to them.
Simetana, J., & Asquith, P. (1994). Adolescents' and parents' conceptions of parental authority and personal autonomy. child Development, 65, 1147-1162. Except for personal issues which adolescents felt were only their business, all other issues were seen by both groups as subject to parental authority. Such issues dealt with choice of friends and moral/prudence issues. Adolescents also viewed parents as being more permissive and authoritarian than did either mothers or fathers.
Strassberg, Z., Doge. K, Pettit, G., and Bates, J. (1994). Spanking in the home and children's subsequent aggression towards kindergarten peers. Development and Psychopathology, 6, 445-461. Least aggressive children come from homes in which both parents refrain from aggressive punishment, whereas spanking by either parent is associated with higher levels of aggression from the child in preschool. Spanking failed to promote prosocial development in every case.
Wallace, P., Gotlib, I. (1990). Marital adjustment during the transition to parenthood: Stability and predictors of change. JMF, 52, 21-29. Marital adjustment peaked for men and women one month postpartum, followed by a significant decrease at six months postpartum. For wives, the best predictor was their level of marital adjustment during pregnancy. For husbands, prenatal level of marital adjustment was the best predictor.
