2 month old not gaining weight

Hello everyone my name is Marissa, I created this because we’ve been in and out of the hospital the last 3 weeks due to our son not gaining weight. It’s been putting a really big toll on us as we have 2 other children as well. Masons father has missed quite a bit of work and paying for child care for our other children during this time. Also food/gas/formula costs is just getting to be a lot. I don’t know medical standpoint what we will be looking at but we appreciate any and all help during this time to make things less stressful and easier when we are able to go back home. Currently the formula he is on is about $60/can but he doesn’t tolerate the powder one as well as the ready to go one so I’m thinking it’s gonna cost more. We have also been purchasing breastmilk because he seems to do a lot better with that but still projectile vomits occasionally. Thank you all for reading and again prayers is appreciated if you can’t donate.

thank you everyone for taking time out of your day to read this.

update 2/25/24 got to see the GI specialist & have a scope of his throat tomorrow morning scheduled! Hoping to have some answers soon!
