This is going to sound weird but google isn’t helping me out ha. DS is 20 months old and has an innie belly button. Tonight as I was changing him into pajamas I noticed the inside of his belly button was bright red, a bit wet looking, and like one flap of skin on it had sort of moved / the whole thing was more open than it had been in the past. Anyone else experience this? It didn’t bother him when I touched it, I’m just not sure what to put on it!
