hi try him on goats milk could be a lot better for him. just goggle this is goats milk lactose free for more info. hope it helps him. good luck
if you are lactose intolerant can lactose free milk still upset your stomach? if but lactose free yogurt does not? . dr has put my toddler on a lactose free diet to see if he can help stop the diahrea/loose mucus stools he has. lactose free milk still seems to go right through him but lactose free probiotic yogurt seems to be ok with him. could something other than lactose intolerance be causing his upset tummy. he did get a stomach flu 2. 5 months ago which is when he seemed to have started with all his tummy issues. the dr said the mucus in his stool suggests lactose intolerance.
