Is It Lactose Intolerance??

Milk is very h*** o* the stomach. When my baby got sick, she had to stop drinking her milk-based formula and switch to gentlease (lactose-free formula) per dr's instructions. Even after she got better, the dr wanted her to continue with gentlease for 1-2 weeks just to give her stomach time to reset. I tried to give it to her before then and she vomited it back up. I then decided to actaully listen to my dr and waited 1-2 weeks after all symptoms had disappeared and then when i gave her normal formula, all was well again. So, in summary, wait a couple of weeks before trying to reintroduce regular milk.

Milk is just horrible for the digestive system when there's an upset/bug going on! Stop it for at least a week after all symptoms of the bug are gone.

You also have to be sure that he really had a bug and not that it was a reaction to the milk.

If he still has stomach issues and/or diarrhea, go to the BRAT diet: Bananas, Rice, Applesauce, Toast (or Turkey). No dairy.

There's no real reason why a child needs milk anyway - just give him a varied diet once his bug is resolved, and really work at keeping him hydrated (water is fine, but you might try popsicles if you can avoid the dyes. If he doesn't have diarrhea, you can make your own from healthy fruit juices (watch the apple juice - it's low in nutrients and can cause diarrhea). Watery fruits and veggies are good too.

Sometimes when a gut is irritated it stays irritated for a long time after the initial cause of irritation has resolved itself.
Don't rush getting him back to normal foods.
Take it slow and easy.
Hold off on the milk for a few weeks and then try it again.
When you do try it - get him onto it slowly.
first week - 1/4 milk + 3/4 formula.
second week - 1/2 milk + 1/2 formula
third week - 3/4 milk + 1/4 formula
and then try him on just plain milk.
Some yogurt might be good for him too.

Hold the milk until he is over the stomach bug.

Hold the milk until he is over the stomach bug.

When someone has the stomach bug, milk increases the production of saliva and mucus, causing irritation . Which is why it's not good to have dairy products when this happens. BRAT diet works best.

Call Pediatrician for more help with this..

If he could take the milk with cereal, then I personally would not think it's a lactose intolerance. I have it. If I have it with cereal, or on it's own, I react.

I've never thrown up. That's pretty severe.

For now, I would just stop giving it to him and talk to your pediatrician.

Ask his pediatrician. He could be having difficulty because of all the possibilities you stated.

I would stop giving him milk for now. Try giving him the sensitive formula that he tolerated before. He has to be completely over the affects of the bug before the doctor can start figuring this out. The bug is one more element complicating the question.

People I know that are lactose intolerant have bathroom issues, not vomit issues.

Poor kid. If he's just recovering from a stomach bug, be VERY careful about the types of foods and quantity you give. Ease him into normal foods. When my son around that age, he went through something similar and I started out by giving him Similac sensitive formula first (even though he had stopped formula already). When he was able to tolerate that I eased him back into regular milk.

I would think if he's over the bug that milk wouldn't be a problem. He shouldn't need cereal in any milk. I wouldn't be giving him milk but maybe try lactose free milk or soy milk. Some kids use goat's milk too.
