My 4 month with reflux help

Jany

Im desesperate the doctor just switch from ranitidine to nexium amd pepcid its been 3 days he stil does'nt want to eat the doctor told us tp put oatmeal on he's milk because the other nigth it wokes me up the sound of him vomiting it was thr most scariest thing ever sincr that day I cannot sleep calm. But any advise I belive the oatmeal its to thick and hr get tired im using nipple 4 dr brown but he drinks 1 ounce or 2 and start pulling the botle and I dont feell like nothing coming out when he drinks .
