Extra gassy babies?

Li

I’ve tried switching formulas up we have used:

-enfamil gentle and the regular yellow can

-similac sensitive

-using gerber good start right now

Is there something else I can do/use? She screams bloody murder when she has to pass gas. We’ve tried the belly messages and moving the legs. Nothing ever comes out. She calms down once she let’s it out. We’ve tried gas drops and gripe water too.

Oh and I will talk to doctor she has 4 month checkup coming up. Just looking to see what’s worked for others.
