Help! Anyone else have this problem? My 2 year old vomits his whole stomach contents every 5-7 days. It can be triggered by anything or nothing, sometimes if he has a cough or if he is upset or if he laughs too much or sometimes just happens when he is happily playing or eating. No warning, he doesn't feel ill beforehand and is perfectly fine after. Have taken DS to docs but they keep fobbing me off with allergies, he does have a dairy allergy but we don't give him dairy. It's getting quite upsetting as when he 'pops' there is literally loads and he gets quite scared struggling to breathe as it all shoots out. Don't think docs are bothered as otherwise he is perfectly robust and healthy. Any thoughts?
