Fisher-Price Rainforest Melodies and Lights Deluxe Gym

I got this play mat as a gift at one of my baby showers. It's extremely colorful and bright, with lots of toys attached. We started using this with our son when he was 1 month old, and he immediately loved the music and watched the lights. This entertains him and even calms him down when he is fussy.  He's six months now and is constantly playing with it.  He rolls around hitting the hanging toys and talking non-stop for at least 30 minutes.
