**Lithium (for manic-depressive illness): Excreted in human milk.
**Methotrexate (for arthritis): Can suppress the baby's immune system.
**Drugs of Abuse: Some drugs, such as cocaine and PCP, can intoxicate the baby. Others, such as amphetamines, heroin and marijuana, can cause a variety of problems, including irritability, poor sleeping patterns, tremors, and vomiting. Babies become addicted to these drugs. (Let’s face it…you shouldn’t be taking these anyway!!! Stop now for the sake of your little one!)
**Tobacco Smoke: Nursing mothers should avoid smoking. Nicotine can cause vomiting, diarrhea and restlessness for the baby, as well as decreased milk production mommy.

Why risk it?
