Yeah there milk sucking blisters u may see a area that just peels away. It's cos there lips are very soft and like your nipples they need to toughen up a little , all of my babies I breast fed got them after a week it stops normally

Oh alright thanks xxx @suzie80

I'm breast feeding @suzie80

Are u breast or bottle feeding? Babies can get milk blisters and areas peel off it doesn't last that long
