Your brain and body do feel the
effects of the drug nicotine in the tabacco. Your
baby will feel it to, and it may or may not effect brain developement.
My mom had 2 sisters. Of the 3 mommys, one smoked cigarettes and drank a little during pregnancy. The 2 mom's who did not smoke or drink had multiple healthy live births where all kids went to college...school teachers, attorneys, business peeps. The aunt who smoked and drank had low birth weight babies.
