1st Birthday....Help!

Fellow moms: what are some fun activity ideas for a first birthday party? We are having Tatum's party at our house and our house is small. It is hot outside so I am trying to come up with some indoor activities. Let me know of any that you did or have seen done that worked well!

I am already planning to do a craft table where the kids decorate a paper necktie (we are doing a "little man" themed party).

I'm open to any and all suggestions! :)
