Talk to doctor. But I had this with my baby. Turned out it was a protein sensitivity with cows milk and soy. I’m EBF with my 7month old. But once I cut out cows dairy and soy, he perked up as the happiest baby. Gripe water helped. But didn’t stop the source of the issue.
My baby has started doing this. Refusing feed and screaming, red face, and then suddenly will take the bottle. I think he’s going through a change personally. Whether it’s a physical growth or a mental growth. He’s never been like this
he could be colicy! i would try mylicon
