It looks very swollen to me, I’d call the doctor.
My LB looked similar spoke with the health visitor who confirmed it was fine and it just resolved itself over a week, just check with your health visitor or a dr to be sure & put your mind at ease more than anything
My daughters belly button looks almost like that too, but not red. I’m going to ask dr about it.
That does not look normal. I would have him seen asap! Just to make sure there is no infection!
Asked the Dr, she felt for a hernia and there wasn’t one so no worries. You could have your Dr. Check it out and see if it feels like no hernia too. But also just to make sure it’s not infected.
Does not look normal to me but it’s probably ok. Might be a hernia or something? I am not sure but I would get it checked out to be sure
