At 12 weeks babies tend to Chew they're hands more. That's part of expected development. However, it might be she's sticky them into far and causing herself to gag. My LO does that a decent amount
She has screamed 3 times today at the start of a feed.. so I wonder if it's the letdown...
I’ve had this loadsss- my baby does have reflux and is on Omeprazole but it doesn’t always solve the on/off issue. I showed a video to a lactation consultant and she said it looks like my baby is doing it out of discomfort so is likely the reflux or gas pains. I’ve never had concerns about oversupply, more under- so I don’t know about that side of things.
My son has the same plus projectile vomiting. The GP prescribed gaviscon, which helped for a few weeks, but not is is back
