Please Help with Stinky Green Poop

I also had an oversupply. And my son had multiple food allergies- but not to milk. It's time for an elimination diet- nuts, eggs, dairy- all the biggies.
I would like to give you some encouragement- while I tackled my oversupply early, the green gassy colic didn't end until I stopped breastfeeding. Since he was allergic to multiple things, I couldn't pinpoint any one cause and he and I were just absolutely miserable. After switching him to formula, he improved almost overnight. Later, once his food allergies were uncovered, I felt HORRIBLE that I had subjected him to all that pain and misery. Just know that I am NOT advocating formula by any means- just saying that sometimes it's extremely difficult to know the cause. But all signs you mention point to something in your diet.

It takes longer than 9 days for dairy to leave your system completely. It takes a full TWO WEEKS/14 days. A true dairy elimination diet is a minimum of four full weeks. So don't discount eliminating dairy as the culprit yet. It could still be part of the problem.

Keep a food diary and a journal of when the baby eats, poops, urinates, sleeps, etc. You'll start seeing patterns in the journal. You just need a pen and a spiral bound notebook.

Check KellyMom.com for common foods that are triggers for gassiness in breastfed babies as well as other common allergens. Remove those things from your diet and note what you're removing from your diet and when. Again, this is called an Elimination Diet, but do it appropriately per KellyMom.com.

My DD had the same problem, and for us it REALLY WAS the milk!! It took about 2 weeks for me to notice a difference in her, but when I did it was like night and day. I had to keep most dairy out of my diet until my DD was around 5-6 months old, and by then she had outgrown her milk protein allergy.

I also had a REALLY forceful letdown... To the point that my poor DD would choke trying to eat. I had to get my milk going, then let it run (spray more like) into a rag until the pressure let up.

I also took the opportunity to start pumping and storing my oversupply... I would nurse my DD on one side only, (Rarely, she would get full off one and I would let her finish on the other.) and pump the other when she was done... Next feeding I would switch sides. I was able to build up a nice big supply, which came in handy when I went back to work because my supply PLUMMETED for about a month during that transition.
^^ha ha. Didn't notice you were doing that already the first time I read. lol.

I suggest you start with burping MUCH better. Don't gently rub his back. FIRMLY pat his butt and back. Make sure you get several good burps.

Also, what you're eating affects his tummy (of course). So if you're eating something regularly, cut it out for a few days and see if that doesn't help. Basically, figure out what's affecting him by trial and error.

Best of luck!

I suggest contacting a lactation consultant, if you have any IBCLCs (international board certified) in your area, start there. If money is an issue many hospitals offer free breast feeding support groups staffer by LCs. Also, have you checked out the kellymom website, or Dr. Jack Newman's site? Both good sources for bf issues. I wish you the best!
