My ds (11yrs) has always loved milk. But over the last year or so I've noticed sometimes if he has it in any quantity he seems to have stomach problems within an hour.
3 times in the last term I've been called into school. He has the runs, crampy stomach, feels ill. I get him home and within a few hours in bed he's feeling better. Of course the school's first thought is that it's a tummy bug. Mine too. But I'm starting to see an association to milk.
This doesn't happen all the time. Indeed he has it every day on his cereal with no problems. But not infrequently he has this; it happened again yesterday. The last time he had a big milkshake, up it came again within 5 minutes.
I'm 100% sure there are no problems at school which could account for this. If anything he seems annoyed at being sent home. Also he is
at me cos I'm suggesting he should maybe cut back on the milk, because he really likes it.
