Baby screaming when bottle is in mouth

Am

My 11 day old has started having some really concerning feeding issues. He’ll scream that he’s hungry but when we put the bottle in his mouth he sucks for a few seconds and then starts screaming again. A lot of the time he’s not even swallowing what he drinks so it runs out of his mouth when he starts screaming.

We started him on Similac Pro Advance but switched to Similac Total Comfort when he started doing this. He did well for a day it so but now it’s back to the same thing.

We’ll be talking to his pediatrician, but has anyone else experienced this?
