Hello, my 3 and a half year old son has been having diarrhea since 6 weeks. It has been on and off with regular stools in the morning and loose motions in the evening. We tried the usual solution for diarrhea - water, banana, apple, rice and toast and yogurt. Then we stopped dairy (milk, cheese, etc) but there was no effect. Eventually, about 2 weeks ago, he got constipated and we had to use Miralax to flush out stools in his colon. He is back to the same state now. No other symptoms - he plays, eats well, drinks and has no fever or stomach pain. Stool tests are negative, no worms. We are waiting for blood test results for other infections. Loose stools were with farts and gushed out. Sometimes its only watery and/or foamy liquid. Any help is much appreciated.
