I just wanted to share this really awesome helpline I read about this morning. I called and double checked that all my medications that I'm on after delivery are in fact safe for breastfeeding. It was really nice to have access to the information in Dr. Hale's book, Medications in Mother's Milk when I don't have a copy of the book.
The number is 806-352-2519 and this is their website with some information about what services they offer. It's a great free service, I hope someone else will find it useful as well.
