Is it safe to eat candy while pregnant?

Yes: In moderation. Preg metabolism is slow and weight easy to gain hard to loose.

Mostly yes but: Depends on whether the candy has anything in it that might be toxic to baby. Most are not but i recall a few that have significant amounts of caffeine in them & any excess could bother baby.Consumption near the time of birth could cause an excessively jittery of fussy baby. Sugar by itself can lead to blood sugar problems in some moms & effect the baby in return.

Yes: The calories in candy should be incorporated in your overall dietary and caloric needs. It is safe because the developing baby will not be affected by whatever candy you eat.
