If the younger siblings can't come, then I guess you're thinking the moms should drop their 5 year olds off and not stay for the party? My oldest is three, so don't know if i'd be willing to drop her off and trust in the supervision provided. I'm thinking we wouldn't go at all if I couldn't bring baby sister. As for activities not being age appropriate, the younger one's simply won't participate in things that are too advanced. I don't really see an issue there.
