Baby Indigestion Help

Brooke
My daughter is 1 week old and breastfeeding. My supply is quite abundant, so I am trying to make sure I pump before I feed her so she isn't overwhelmed and overeating. Still, she seems to have a hard time burping after feeding, and she will spit up quite a bit of what looks like curdled milk a couple of hours after she eats. She's having plenty of wet and poopy diapers, so I know she is getting enough, but I'm trying to figure out why I can't get her to burp. I burp her after each breast (she usually does 10 minutes per side), but I usually only get one good burp in 20 minutes' time. Anyone have any suggestions?
