There have been no studies on how psych medications consumed through breast milk. They can't be done as it would too risky for infants. If it was me...and I nursed for two years...I would give up the nursing to stay stable on medication. There is no way to know if your medications would damage your child's health. (Oh, at the time I nursed I didn't know I had bipolar and had minor symptoms so I wasn't on medication).
