BB has been popping on and off nipple for a few days. Just thought it was a phase. Also thought baby had reflux because he was vomiting curdled milk substance. He goes through these spells (not every day) which I thought were pain from the reflux and he cries constantly and tonight was one of those nights. He was going completely rigid arching his back into a U formation. He would latch on only to pop off and scream. My husband suggested we try formula. I didn't think it would help because I tried bottle feeding BB breastmilk and he wouldn't take it. He is now working on his 6th oz of formula. Was I starving my baby and didn't know it? Is that why he was having those episodes of crying? I can't help but feel like a failure!! He's been voiding 6-8 diapers a day as well as stooling fine. I thought everything was OK.
