DS1, aged 9, has to have a barium meal to see if he might have a mal-rotation of his bowel.
Has anyone else's child had one and if so, how do you get your child to swallow not very nice tasting stuff, especially, if, like DS1 he never tolerates drinking or eating anything that he's not 100% OK with and will probably gag and refuse to carry on drinking it?!
This is part of investigations to find out why he vomits so much , in any case.
