This will be called a tentative truth. Smoking during pregnancy has already been linked to low birth weights, stillborns, and premature delivery. However, the link between smoking and miscarriage is still relatively tentative. Though some studies have found a potential causation link between smoking and miscarriage, by proposing that women who smoke more than 10 cigarettes a day do increase their risks of miscarriage.

By two months old, an infant is able to recognize both people’s faces and voices of his or her parents and close family they see regularly. They should smile at these familiar faces and turn their heads towards voices they recognize.

Newborn babies are experiencing a totally new environment. The feelings, noises, and sights are entirely new to them, which can be uncomfortable and unsettling. However, things they do recognize are the sounds of his or her parent’s voices, and the feeling of being held, similar to when they were snug in the womb. Holding your baby and speaking to your baby will help to teach him or her how to regulate their own emotions and calm themselves down.

The risk of high blood pressure during pregnancy is about double for women over 35 compared with younger ones; hypertension affects about 10 to 20 percent of pregnant women in this age group. Gestational diabetes is two to three times more common in women over age 35 than in younger women, and recent studies show the risk is even higher if the woman has gained weight over the years. Age 35 to 39 is also when women are most likely to have twins.

Prolactin is a hormone that plays a role in fertility by inhibiting follicle stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH), the hormones that trigger ovulation and allow eggs to develop and mature.
