My little guy has loved this gym since he was 8 weeks old. At that age, he couldn't really interact with it, but loved looking at the lights and the butterflies, which I had to manipulate manually. Now that he's almost five months old, he enjoys hitting and kicking the elephant rattle and swatting the parrot toy! His favorite parts have got to be the removable toucan and monkey--they go with him everywhere! And they're so easy to wash (and they air dry beautifully) after he's chewed on them. The mat washes nicely as well. 

The rainforest sounds are gentle and soothing and have lulled him to sleep...
