smoking while your pregnant is very dangerous to the baby it can cause the baby to have a low birth weight, to be premature ,and have a predisposition to getting addicted to cigarrete's as well. plz do not smoke during your pregnacy i hope this helps
Not only does it cause low birth weight but the baby's lungs will be underdeveloped and the baby will have respiratory problems for the rest of his life. Remember your health too. It can cause premature labor, you yourself can develop lung problems, and you're more susceptible to infections. I hope this helps you!
