We are BF and supplementing but every once in a while, he will pull off at the boob and start screaming bloody murder, latch back on if i push his head towards it, suck for a min then pop off and scream and cry again! After a couple minutes of this, we both get stressed so we go to the bottle - either pumped milk or formula. I actually went to the dr about this and she said it could be his reflux, and if it persists she will consider zantac for him - but he stopped and was doing fine until today, at his last feeding - he was screaming! He is not a screaming kind of baby either, he hardly cries like that, if ever, its like my milk is causing him pain, it's really hard to see him cry like that. Has this happened to anyone? should have the dr put him on zantac to see if it helps?
