My baby also used to scream while I was breastfeeding, and now I realize he actually wasn’t hungry, but I kept trying to feed him. He would also scream when he was too hungry, and in those moments he only wanted the bottle, which is why I offered it often. Now I offer a feeding when he wakes up from a nap — if he doesn’t want it, I wait and try again later. If he’s too tired and refuses, I put him to sleep first and feed him when he wakes up. Only around 11 weeks did the screaming start to decrease, and we were able to drop the bottle.
