- If you smoke, the best thing you can do for yourself and your baby is to quit as soon as possible. If you can\’t quit, it is still better to breastfeed because it may protect your baby from respiratory problems and sudden infant death syndrome (SIDS). Be sure to smoke away from your baby, and change your clothes to keep your baby away from the chemicals smoking leaves behind. Ask a doctor or nurse for help quitting smoking.
- You should avoid alcohol in large amounts. According to the American Academy of Pediatrics (AAP), an occasional drink is fine. The AAP recommends waiting two or more hours before nursing. You also can pump milk before you drink to feed your baby later.
- It is not safe for you to use an illegal drug. Drugs such as cocaine, marijuana, heroin, and PCP can harm your baby. Some reported side effects in babies include seizures, vomiting, poor feeding, and tremors.
