My baby’s daycare teacher wonders if my daughter has acid reflux. ( I also wonder this ever since she was a few weeks old)

We have a 4 month appointment coming up and I want to talk to her pediatrician about it.

Last time they said as long as she is gaining weight they don’t worry about it and that eventually she will grow out of it after 6+ months..

She spits up a lot after every single feeding, sometimes hours later.. recently I watched clear liquid come out of her nose and her mouth during a spit up and she was extremely uncomfortable.

If you have experienced this- or baby acid reflux what did you do? What medicine were you prescribed? I want to do research before her appointment. I just want her to stop being miserable 😩
