Oh, loot bags. You are a tougher nut to crack than I expected! How to find items that are in keeping with the party theme, that 3 year olds will like, that parents won't throw out, and aren't prohibitively expensive.....mon dieu!
In the end I decided on:
- A paddle board (those rackets with the elastic cord with a ball attached on the end)...too advanced for 3 year olds?...maybe
- Sports stickers
- A twisty straw
- Lolly pops and pop rock candy
- A bouncy ball
- A sports medal
....all from the Dollar Store, Bulk Barn, and The Party Store.
