I'm not sure when Micah will grow tired of this playmat, but for now, he LOVES it. This kid loves to be on his back. If he is fussy, I know that he must be wet, hungry, sleepy or want to be laid on his back. It is so sweet to see him kick his feet and get all giddy when I put him down there. He stares at the objects dangling in front of him like they are the most interesting things he has ever seen. But, you know, he is only 3 months old. Maybe they ARE the most interesting things he has ever seen!
