While cocaine's effects are usually immediate, the effect it can have on a fetus may last a lifetime. Babies born to mothers who smoke crack cocaine during pregnancy -- so-called ''crack babies'' -- usually have their own set of physical and mental problems.hile cocaine's effects are usually immediate, the effect it can have on a fetus may last a lifetime.

Last year, there were 27,000 babies born to momâs over 40. The study was done to help women understand their fertility lifecycle. They still argue that the safest time to have a baby is between 20 and 35. In fact, 30% of 35 year olds need more than a year to conceive while only 5% of 25 year olds need this much time.
In the low-risk pregnancy group, they estimate it to be between 38 and 39 weeks of gestation. In women 35 years of age and older, they estimate the optimal gestational age right at 39 weeks of gestation.In women with hypertension, they estimate the optimal gestational age to be between 39 weeks and 2 days and 40 weeks and 1 day.Finally, only women with diabetes had an optimal gestational age estimated to be greater than 40 weeks of gestation, between 40 and 41 weeks.Interestingly, this last group is the one that is commonly induced early owing to ongoing increased risk of stillbirth as well as concern for macrosomia.stimate the optimal gestational age of delivery with respect to maternal and neonatal outcomes. Although they are only powered to look at a few of the feasible outcomes, they consistently find that the overall optimal gestational age is less than 40 weeks of gestation.
