DS (5.11) has been sick a few times over the last few month, but not due to a bug. It typically happens just after or while he's eating, he complains of stomach pain and cramps (so bad he cries) and then a few minutes later is sick, bringing whatever he's just eaten back up.
I think it's happened 4 times in the last 2 months and is a new thing before that. Most recent was last night when he was eating a tomato - that came straight back up.
I am worried, will take to the Doctors, and DH seems to think it's where he's eaten too fast and has trapped some air in his tummy. Any ideas?
