He s 5, 40 lbs and has no medical history. Very healthy boy. He has a bloated tummy. He had his Kindergarten shots 2 weeks ago and that next day he had vomit and diahhrea, and our whole family got a virus but his lasted a LOT longer and is still having tummy issues. He s been very gassy and our Doc put him on Lansoprazole once a day. It s NOT helping. He woke up last night very irritable and I ran him a warm bath and he finally started passing some gas, but he s the same way tonight. His tummy is huge! What else can I do? Would baking soda and water work? Should I go to the store and buy another over the counter gas med? Not sure what to do.
