Myth: I've heard that if you don't drink a lot of water that the baby will be dirty.

Truth: Amniotic fluid is an amazing product! It completely replaces itself every three hours, even after your water has broken. What mom drinks can help or hinder its production, but it is definitely not all about her hydration. The baby does urinate into the water, and skin cells from the baby are also sloughed off into the water. This is what amniocentesis uses to determine gender and chromosomal make up of your baby.
