The first question an expectant mother often gets asked is "do you want a boy or a girl. and her answer is usually "it doesn't matter as long as it's healthy."

Obstetrician Richard Bloy explains that from the moment that stick changes color and a woman finds out she's pregnant, she should start making some changes to her lifestyle. Most notable: diet and exercise. "We love exercise during pregnancy because healthier mother, easier labor, much healthier pregnancy. We recommend continuing exercise that you're doing. We don't necessarily recommend starting some new power program during pregnancy."

Dr. Bloy says that unfortunately expectant mothers need to watch their diets pretty closely. That just doesn't mean avoiding things like caffeine, that means keeping sugar to a minimum and being sure that you get all the nourishment you need to make your baby a healthy one. "The diet is probably the number one most important factor. Prenatal vitamins are designed for just that. So the one or even 2 prenatal vitamins a day, depending on the circumstances, give you all the right nutrition, including folic acid."

Expectant Mother Saundra Best says, "They're hard to take. And they don't taste great and they're huge but they're really important."

Dr. Bloy reminds us that it's never too early to start preparing for the healthiest pregnancy possible, and you can make some important changes before you even get pregnant. "We can actually use things that can prevent birth defects, for instance, folic acid. Or if we can help control the mother's blood sugar before if she's diabetic we can prevent major problems with the baby during pregnancy."

You should let your doctor know if you're trying to get pregnant, so they can go over your full family medical history for any potential problems.

Babies born to mothers who received no prenatal care are three times more likely to be born at low birth weight than those whose mothers received prenatal care.
