It's usually right after she eats. I'm assuming she's eating too much? Is that right? I try to get her to nurse for 15 minutes on each breast. She always does 15 minutes on the first one and usually 5 to 10 on the second. Most times I can get her to burp in between breasts. Is she spitting up because she's not able to burp? Sorry about the dumb question. TIA!
