Some women are concerned about the health of the baby's father. In recent years, more attention has been given to the paternal contribution in pregnancy. We now believe if a father is older than 40, it may increase risk of Down syndrome, although there is not a great deal of evidence to support this theory. A father's drug habit at the time of conception may also influence the outcome of your pregnancy. Evidence is scanty, but there does appear to be an effect.
Many women use artificial sweeteners.
Aspartame and saccharin are the two most common artificial sweeteners added to foods and beverages. It is used in many low-calorie foods and beverages to help reduce calorie content. Aspartame is a combination of phenylalanine and aspartic acid, two amino acids. Recently, there has been controversy as to the safety of aspartame. I advise you to substitute foods that do not contain the sweetener.
