He's only 4 months old, but this is by far his favorite. It makes all sorts of sounds and has a lot of different colors to capture his interest. His face just lights up when I pull this toy out. He loves to suck and chew on his ears, which make a crinkle-sound.

Only negative is that my baby managed to pull the clip off within a week of playing with him (made me wonder if this is a quality product). On the bright side, the clip annoyed me and I wanted it off anyhow.
