Lip tied issues

Chelsey
So my 3 week old has a lip tie she has an apt to get it fixed on the 23rd. My issue is that she spits up after every feeding and I'm worried that she's not getting enough. She almost always has a wet diaper and just recently has started popping less. I'm really freaking out about this and am thinking about calling the ents office everyday until they move her apt up.... Any advice?
