How to stop my baby vomiting ..,,, ?

My baby vomits every day from reflux and it’s getting so exhausting. He doesn’t spit up anymore (he’s 9 months) but instead he has reflux vomiting. I’ve read that it’s bc babies have an immature esophagus and most grow out of it by 1 year old. But I am cleaning up massive amounts of vomit daily and I hate that he is throwing up an entire meal daily, sometimes two, and it’s created stress around keeping weight on. So far he is still “ok” on weight. He was always around 10-15% weight for age, so he’s skinny but he’s still tracking there so he’s keeping enough down to stay stable. But this vomiting is bad, it’s like 3 cups of volume and I have to constantly bathe him, wash the high chair, shampoo the couches and the rugs, clean the whole bed etc every day. I just feel bad for him and I can’t EVER leave the house because of him vomiting. Its isolating and frustrating.

Has anyone else baby had the reflux vomiting and when did it stop? I’ve read they don’t like to medicate it unless it goes past 1 yr old or if there is weight loss, since most babies grow out of it and the medications can impact the digestion long term, but it’s become so stressful and frankly controls our life. We were supposed to go on a vacation but we can’t go bc how will we deal with vomit in the car and a hotel without the constant access to washer/dryer which I have to do 3 loads daily 😭😭😭😭 I can’t even go to the grocery store with him - exhausted mama needing to vent and hoping to hear babyothers experiences
