Spit up help!

Victoria

My little one has always been a spitter but I thought it was supposed to get better as he got older. Lately it’s been worse. He spits up fountains all the time. The worst is that it has been waking him up from his naps and it takes forever to get him to sleep at night. I’ve gone dairy free for four days now to see if that helps with spitting up from nursing. So far it hasn’t. I also supplement with formula. Anybody have a baby who spit up a lot and did something to help it? I’m getting desperate.
