Baby throw up

Are there any remedies are helpful tips for a baby who throws up a lot? I’ve told my pediatrician but they don’t really seem to do anything or say anything about it my 10 week old baby boy throws up a lot with feedings like projectile it has pressure behind it and it doesn’t usually seem to hurt him but I’m wondering what’s making him do that and how to help him from doing that even after he eats I have to make sure he’s up rate for a long time or he will continue to throw up
