My daughter is almost 5 wks old and gets these little red bumps that get darker red when she bf. She sometimes let's out a cry in the middle of feeding which makes her sometimes choke! When I burp her she usually spits up and then seems to get better. Sometimes I feel like it's her tummy. So how can u tell if the food your eating hurts her belly or is allergic to it. Please help it makes me so sad to hear her high pitch cry.
