I might be wrong, but I was always under the understanding that probiotics were supposed to eliminate any form of diarreah or runny poops. Ds's poop has gotten more solid since we switched to raw milk and he's begun drinking kefir (with berries of course
). Perhaps the probiotics you are using are no longer active.
As far as the lactose intolerance, ds was hospitalized twice at six months for internal bleeding due to dairy products in MY diet. He is doing absolutely EXCELLENT now (at 2 1/2) on the organic, raw dairy. Something to keep in mind is that kefir is the result of a culturing process that eliminates lactose in it. It was a nerve wracking decision, but I had reached the end of my rope and ran out of options for him, dd and myself with our digestive issues. The only regret I have is that I didn't do it sooner.
