Final answer:
Smoking during pregnancy increases the risk of complications for the developing baby.
Step-by-step explanation:
Smoking during pregnancy can have serious health risks for both the mother and the developing baby. One of the risks associated with smoking during pregnancy is an increased chance of the child developing certain health conditions. The longer a father smokes during the mother's pregnancy, the stronger the risk that their children might develop complications such as premature birth, low birth weight, stillbirth, and sudden infant death syndrome (SIDS).
