So, I was finally able to get the wheels in motion to do my son's first "friends" party this year (turning 5) and a friend of mine, whose daughter is in the same class as my son, suggested that we do their party together, since all the kids seem to go to the events.

My son was on board with it, but I am worried that some parents might think it's weird...am I over-caring? FWIW, we'd be having the event at a kids activity place and we'd be splitting the cost, plus probably paying a surcharge for having more kids than included in the package (which I am totally fine with, there are 11 kids in total in my son's class).
