I have a 2 month old baby and just had a revision 2 days ago. I'm exclusively breastfeeding. My surgeon said it was okay to breastfeed right after waking up from the anesthesia and that only a tiny amount from the pain meds would go to the baby. I have felt really great and was able to get up in the night and feed my baby the same day as my revision. I have only taken the minimum pain meds and not very often. It has been so much easier than I expected. I can tell that my milk supply is about half what it used to be, but it seams like my baby is getting enough. I'm supposed to be on clear liquids for a week, but have already added in some creamy soups to make sure I have enough liquid and calories for my baby.
