Umbilical stump??

Okay so Kingston is a week & 2 days 💙 he’s peed on his umbilical stump (like a normal boy 😂) and it was gooey at the very inside of it. His doctor told me to take a q tip and just quickly clean in it and then leave it. Well I have and for the most part it’s dried back up but now it looks like it’s about to fall off, but like it’s gonna fall off but not at the base?? Does this look okay..? If it does fall off like it looks like it is, will the inside part fall off too?? 😅 first time mom here..
