A good friend of mine was told she HAD to stop breastfeeding because she was having her hip replaced. The dr told her that because the hip replacement was metal on metal that the "ions" in her body wouldn't be good for the baby. Her baby is 3 or 4 months right now and she already is dried up. When she told me that today I asked her if she wanted to stop and she said no. I told her I'd find out some info for her and let her know ASAP. She is more than willing to pump to get her supply back. Any help is appreciated...her surgery is next week.
