Ball/Foam Pit. Small plastic pool plus cut up pool noodles! Less than $15. The girls might be too old for this now, but it's a super cute idea for a future baby... Or maybe a 2nd birthday gift for a cute lil boy next summer....? @Hollee Han
"Whenever we have play dates, the ball pit is one of the most popular hangouts in the playroom. Seriously the kids LOVE it! We've had this ball pit since Jake was 6 months old and it's still one of his favorite toys. You can easily make your own with an inflatable swimming pool and pit balls (we used 200). "
