Does age of parents affect baby's health?

yes it does. a mother who is pregnant at a later age is more prone to health issues such as diabetes, preeclampsia, both of which can harm the unborn baby, as well as is more at risk for ectopic pregnancy or miscarriage. however, not all women who are pregnant at a later age may develop these complications. being pregnant later can also increase the risk of chromosomal abnormalities in the baby, such as Down's Syndrome as well as Edward's Syndrome. there are many health issues that can definitely affect the baby if the pregnancy is late, and also affect the mother. http://www.acog.org/Patients/FAQs/Having-a-Baby-After-Age-35
