got this for my son when he was around 2 months old. Is now 6 months and definitely his favourite. Small size so could manipulate it quite early on, and now lots of things on it to chew - especially the two feet which are perfect size for his mouth!
He hasn't discovered the squeaker in the middle yet, but the ears crinkle and the rest is chewable - just what a baby wants!
Can't be put in a washing machine unfortunately, but washes ok by hand, although one of his ears seems a little too chewed for total cleanliness now!
