ive been pumpin milk lately but....when my LO was getting formula mostly...and ALWAYS burped between 1/2-1oz...several burps even...sometimes if laid down for diaper change shed throw up out her nose n mouth choking her id have to suction her nose to get her able to breathe. my dr says this happens...well...obviously but why? he says sit her upright a while after feeding...does help..but...whats causing it? any one have this happen? i do remember once it did with my now 19 year old but its scarey seeing your baby lookin like shes gonna choke to death an cant breathe,,,,,they told me with him it was reflux? but not sure with her... she didnt have these problems until increase in feedings as dr was concerned at birth she was 3pounds 4 1/2oz ate fine but wanted to slowly increase them...now 6weeks old shes takin bout 3-4oz pumped milk. if she eats n lies on my chest tho shes fine? only when laid on her back...N E IDEAS?
