Kids activities

Arianne • pregnant with baby #2. due November 2nd with a Lil prince💙
So I am having my babyshower in about a month and it is going to be co-ed with lots of kids attending. I was wondering if anyone knew any ideas to keep the kids busy for a few hours? They could play some of the games but i know kids need to be occupied or they start getting wild lol. Thanks in advance.
