Turning 5!

My son is turning 5 Feb 2nd. Usually we always do family dinners, I’d decorate for him & it would be all his family there.

I’m not sure if this time we should invite his friends? What if he doesn’t have that many? lol, I don’t even know who he interacts with at school! I don’t know most of the parents either. 😅 I’m 25, he’s my oldest so I’ve never done anything like this before! Any ideas?
