Ok so here is the thing...my one month old has been just recently (since yesterday) throwing up after every other feeding. I am not sure what it is but it is scaring the doo doo out of me! This is not the occasional spit up its a forceful vomit where he throws up his whole meal. It usually happens around 15 minutes or so after his bottle (I pump his milk and he takes it by bottle). Does anyone know why this might be? How could I tell if he has a dairy allergy or if it is reflux? He does get the hiccups quite often and they are quite strong (I don't know if this has anything to do with the throwing up but thought I would mention it). I also noticed that his poop has been firmer than usual. Could he be constipated? Would constipation cause vomitting? Any advise would be appreciated..thanks for listening.
