My little one does this too she’s got reflux
If they’re drooling a lot it’s most likely just a lot of saliva mixed in with the milk. Mine has the same when he spits up
Mine has this since she started teething and angrily shoving her hands in her mouth all the time creating a lot of saliva!
My LB has this, and so did my first born and they both had/have reflux, my LB will do this when he's due a feed xx
My girl is 11 weeks and she was doing this frequently, turns out she had reflux. We have been thickening her milk using carobel for the past 3/4 weeks and it hasn't happened again since. X
Mine does this, I just put it down to a mixture of dribble and milk, probably because of teething xx
