You can buy rice milk that has been fortified with calcium. Also they sell orange juice with calcium especially for people who are living on dairy-free diets.

There's also hemp milk which is creamier than rice milk. We combine the two together because the result is closest to 2% dairy milk.

Have you tried almond milk? Once your child has had any dairy substitute for a week or two, he'll be totally used to it. He won't miss cow's milk at all.

First off I suggest you always take this up with your physician or the people of the consultation bureau if your country has such a thing. The consultation bureau is a place where you take your child to get weighed measured and checked up to see if it's growing according to the standards. Consulting your physician is always a must when your child is ill they can tell you if it's healthy for the child to try this methode. Nowadays there are many milk replacements it's really a matter of finding out what he likes. Soy milk doesn't taste very yummy I know I've had my share of it but nowadays there's yogi drink soy milk and chocolate soy milk too which taste like the real thing. Try adding a little sugar or lemonade to the soy milk, a sweeter taste can make a child drink something it previously didn't like. It worked for my brother who was lactose intollerant. But yeah it would be best to see a doctor first. It could just be that it needs it's tonsils removed to cure all the problems that was the case with me. it could also be that your child may have a middle ear infection if the earinfections and colds are paired with painful ears and trouble breathing, it's well worth looking into because with a simple procedure of incerting tubes in the child's inner ear they can cure his ear infections before they become worse. I had this middle ear infection problem too so I know the child will feel much better after and the colds and ear infections would close to disappear. Again I suggest talking to your doctor and the ear nose throat specialist in the hospital about it. Don't wait too long with a doctor's visit though. Take it from someone who's doctor didn't send her to the hospital on time you do not want your child to go deaf from an ear infection that could've been prevented with a two hour procedure.
