my daughter will be eight in july, she has been having air in her stomach constantly , she complains it makes her feel nausas, she burps and its gone, shes fine, but then again it comes back every now and then during the day, oh it happends about 3 times a day, so far it happens whn she drinks out of a straw or drinking out of a cup without a straw too. i give her tums all the time with this problem that she has, but the thing is when she burps she is feeling better and ok, then it comes right back later that day , what should i do for her, im really concerned.

thanks
