I remember starting my older son on cows milk after he turned 1 He didn’t tolerate it. Apparently this is normal and it takes time for the digestive system to accept the cows milk. Keep in mind he eats yogurt cheese no problem. But cows milk = diarrhea. Now my second son who’s 15mo same thing! I have been giving him homogenized 3% on and off since he turned 1, with no good results. The last 4 days I have been offering it and still diarrhea, his little bum is getting a rash now and Idk what to do. My older son drank soy milk until he was 4 at which time he (finally) started tolerating the cows milk. My 15mo does not like the soy milk, he won’t drink it. I’m breastfeeding still so I’m not worried for his lack of milk in his diet but at what point do I quit and offer again at a later date? I’ve heard 2 wks of this and his system shud start to tolerate it. Any other similar experiences??
