When my baby was born his belly button was an outie and the Health Nurse said a weakness in his stomach muscles were just making his belly button stick out and as it got stronger it would go in. I think she might have even called it a hernia. Sure enough over time it went in. He is now 10 months and over the last couple of weeks it is starting to stick out again.

I'm not worried about it but curious as to why this is happening. Do this mean he will have an outie rather than an innie? Does anyone have any ideas?
