The sooner the better on the invites! With the holidays coming up, people's calendars start to fill pretty quickly.
Considering the fact that you will be doing the party just before Thanksgiving, you could definitely do some fun activities that are indoors and seasonal.
- crafts that are appropriate for their age and could be decorations for Thanksgiving or a holiday gift (think decorated picture frames, mugs, wreaths, etc)
- If you have a basement with open space, consider doing a "fall festival" with bobbing for apples (or the donuts on a string), pinata, face painting, carnival snacks (popcorn, candy apples, hot cider)
- Traditional children's party games are always a hit- "pin the tail on the donkey", "red light/green light", bean bag toss, hoola hoop contest
Google "children's party games" and get creative!
**Also indicate whether or not parents are supposed to stay. If you would like families to attend, you could do a big thing of chili & cornbread for the adults and something equally as simple for the kiddos. If you do not want parents to stay, add something like.... "Mom and Dad, drop them off and get the last minute Thanksgiving preparations finished and we'll see you at 2:30!"
