I have a 3 week old and She seems to spit up A LOT....and a lot more than I remember my first LO spitting up. How do you know if its just normal spitting up or its actually reflux? I feel so bad bc no matter what position I try to put her in she spits up and a lot of times it comes out her nose which completely freaks me out. Today, it had been about 2 hours since her last feeding and she was still spitting up! Help!
