I love Tiny Love's Gymini activity mats. They consistently get rave reviews on Amazon, and they last a long time, too! I bought a (secondhand) Tiny Love Gymini Super Deluxe Lights & Music for Piper and she loved it for well beyond the age I thought she'd be done with it. Even my niece who was 3 years old at the time had fun with it!

That's 40% off the list price of $65! You'll also find the adorable Kick & Discover Gymini for 33% off and other sweet toys for nice prices.
