My daugther is 4 months old and two weeks ago, I learned I am hyperthyroid (again) and need to take PTU. I have read that it is generally considered safe to take while b/f as only a small amount passes to babies, but I have also read that the medication can impact on longer term brain development. I'd like to continue to b/f but only if there is really no risk.
Help? Anyone have more information?
