The favorite toy of Eustache is an activity carpet from 'TinyLove' which has two arches from which little stuffed animals and noisy toys are hanging. He got it when he was about two month old, and it has increased his development by orders of magnitude. He started to reach out for these little toys, and then later for other things around his dipaer station. He looks at himself in the mirror. He spends maybe a full hour in there without getting sleepy or tired or fussy. This is highly recommended. Here is the picture:


(note: the baby is provided by amazon.com, he is not Eustache). We bought it at target, where a mom with a 5 month old in her cart highly recommended it to me: her kid still loved it, even after having spend uncountable hours in it.
