IT shouldn't be the breastfeeding that's causing the trouble. I still have my gallbladder (gallstones and all) and I had the same problem up until he was about 4 months old. You might want to check with your doctor. Mine had given me nexium for a while and that helped me out alot. I haven't had a bad flare up in a while but I can usually stop it by taking some maalox before it gets really bad. I would strongly recommend you check with your doctor, in the meantime try to avoid greasy foods or anything acidic (i.e. sodas, grapefruit, orange juice). I know it sounds crazy but you can also try taking a tablespoon of olive oil with 2 drops of lemon juice 2x daily..for some reason that helped me, for irregularity I found that activia actually does work wonders....if you're having a tummy ache drink some peppermint tea or anise tea those are both safe for breastfeeding and anise does help with the milk flow (really!!) Also, cream of wheat for a fiber boost..good luck
