Smoking during pregnancy can cause babies to be born too small or too early. Women who smoke during pregnancy are more likely to have a baby with a birth defect of the mouth and lip called an orofacial cleft.

Babies who breathe in other people’s tobacco smoke are more likely to have ear infections and lung infections, like bronchitis and pneumonia; if they have asthma, breathing in other people’s tobacco smoke can trigger asthma attacks. These babies are also more likely to die from Sudden Infant Death Syndrome (SIDS), a sudden and unexpected infant death that has no immediately obvious cause after investigation.
