Reattachment after circumcision

Ho

*If you are against circumcision, this is not the post for you. Please do not come here to argue. Thanks.*

We got my son circumcised at 2 weeks old and it healed just fine with no issues. I always would get afraid of the skin being reattached. After it healed, I push back with every bath and if he has a dirty diaper. How do I know if it looks how it should? I think I'm worrying about nothing, but just want to be sure. And if it ends up that it is, how do you remedy it?
