Help!!!

Willow

I have a two week old baby girl and she continues to spit up after feedings. It was bad while in hospital and got a little better once we got home but now she is doing it right after feeding and it has chunks in it. I don’t know what to do. We have tried three different formulas and nothing seems to be working. I literally have to hold her upright during the night due to it. Any suggestions????😞
