You have got to be kidding, Jessica16 . . . right?! No, a poor diet isn't good for the baby. I know people who have had poor diets and smoked cigarettes throughout pregnancy and their babies are fine. But you risk so much . . . there are numerous things that can go wrong. With a poor diet you are more likely to get gestational diabetes, which is really bad for you and the baby. In that case your baby will be at a higher risk for developing diabetes later in life. Now is a great time to start eating healthy - it would be great for you and the baby. Take the prenatal vitamins. They are not hard to get; I get mine at Walmart and they are made my NatureMade. You need enough folic acid in your diet to help protect the baby from certain birth defects, and the prenatal vitamins provide that as well as other benefits. Your doctor should tell you all of this. Taking care of yourself now is the best thing you can do for your baby. By doing so you are potentially avoiding a life full of headaches and troubles; that can go along with caring for a child with special needs. Something to think about. Best of luck to you.
