Is my 4 week old baby’s belly button normal

My baby’s stump fell off around day 10 and it healed very well. He is 4 weeks old and I am wondering if his belly button is normal and when it starts looking like a ‘normal’ belly button? I saw the midwife a week ago and she didn’t comment on it, but my friend’s cousin’s baby has a ‘normal’ looking belly button and she is only a week older than my son?!
