I bought Zemi this play-mat/toy area.
She LOVES it! She bats at the toys and makes coo-ing noises that lets me know she is content. She'll turn her head back and forth and kick her legs about and wave her arms and hands around and actually hit the toys and make them move. She can lie here for up to half an hour, and she even out herself to sleep while lying here this afternoon. She played herself out!
