I know to check with my sons dr and I will but I wanna know what u mammas think..

My son has acid reflux and will eat up to 8oz but spit up 1-1.5oz EVERY TIME!! My supply has gone down. Plus my pump went to shit so I was strictly nursing for 3 days...
My question is..can I add 1tsp cereal (I think is what I saw) to 4oz of breast milk? Thinking that if it has some weight to it it may stay down better or if nothing else make him fuller for longer?

He's 2months on the 14th and weighs 13.1 lb at his visit and had only gained 2lb in a month. Im going back to work soon and only get 2 pump breaks so I'm kinda desperate and don't wanna go to formula if I don't have to.

Thank you mommas!
