Regarding: Hi all, got a question. My son is very small and 2. He is majorally allergic to milk. Me and the dr. are trying to think of high fat foods he can eat that have no dairy. Do you guys have any ideas?? I heard an avocodo is high in fat. Is this true? My son is 2 1/2 and is also allergic to milk. I, too, was running into difficulty trying to keep him gaining weight. If your child really needs fat give him lots of meat, like dark meat chicken, ground beef. I dont' know how healthy you want to be, but a number of snacks don't have milk ie.. Hydrox cookies, Vienna Fingers, Kellog reduced fat pop tarts. Gerber has some fruit snacks that have vitamins. I don't know if you have a Sams Club, but I found chicken nuggets and fish sticks that have no milk or egg in them. I hope this helps.
