DP and I both have innies, but our DSs Josh (17) and Toby (16) have always had outies. Nothing particularly noticeable or anything. In fact, I'd not given it any thought for years.
My SIL and family visited for the weekend and she must have seen both my guys bare chested. Anyway, she commented that they should have "gone in" by now. My reaction was to laugh, as im sure that isnt a thing. But i must admit I don't go around checking out belly buttons, so I'm curious to know. Is it a thing? Did your teens get rid of their outies if they had them?
This looks so silly to type. I should be laughing it off, I hope!
