Thanks a bunch guys. I thought a lot about doing just the cupcake thing when I was planning this. I have another daughter with SPD but she is hypo sensitive, so I'm still kinda learning as I go with a hyper sensitive child.

GCmom- She loves going on the trampoline. I was wanting to let the kids go on that at the party.

I really don't know anyone with kids her age or just kids in general, so I'm not worried about that. She just has a habit of "shutting" down when she isn't used to someone. My cousin who is over 4 or more times a week she still is getting used to. My grandmother can't go near her. Thankfully, I have a pretty understanding family.

I also considered staggering family through out the day but I didn't know if that would be too much on her as well.

Do you all think I should still decorate like I would a party (She loves Balloons) but keep the guest minimal?
