Anyone have experience with an older kid and reflux? LO was on reflux meds as an infant but we weaned at 6 months when we realized it was infact MSPI. He seems to tolerate milk but not soy. So he has been soy free since 18 months old. He is now 3.

He seems to be refluxing. It starts when he is eating and then he starts coughing and then he vomits. He has been doing this off and on for the last 2 weeks.

What do I do for him? How do we stop? What do we eliminate next (this last time he was eating rice and chicken).
