Here's a good reason to avoid cigarette smoke. It could cause you to have a cranky baby.
Researchers believe that babies exposed to tobacco smoke both before and after they're born are more likely to have Colic. The thinking is that cigarette smoke is linked to an increase in a blood protein called Motilin, and high Motilin levels are linked to a greater risk of Colic.
Babies with Colic can cry for hours at a time over a period of weeks. Just another reason to make sure your baby is not exposed to smokers.
