Second Trimester: Water Toys

Backyard Birthday Party Ideas (4 Year Old)

I am planning a party for my daughter's 4th Birthday in August. I want do do something on the easy side since I will be in my last trimester with our second child. I was thinking of just having 3 or 4 of her closest friends over to play in the back yard and have lunch, cake, balloons etc. We don't have any play equipment or yard toys because our yard is kind of small and we can walk to a playground nearby. Can anyone give me ideas for activities or games that kids can somewhat do on there own (with supervision of course)so the parents can...
