I am 29 weeks pregnant and was unable to eat anything for about 6 days only kept down water. I read that missing carbs can cause brain damage to the baby could this amount of time affect her?

Hi peachytraci... welcome to AMHD,

While a healthful diet is obviously important, several days of not eating much will not have an adverse effect on baby. Your body is designed to take care of baby even in some pretty extreme circumstances. Consider the mothers who have weeks of morning sickness, finding it difficult to find much that they can eat.

In some cases the situation is extreme and medical assistance becomes necessary, but since it appears this was a limited time, rest assured baby should not experience any negative result because of it.
