My 4 month old loves it, and has loved it since he was around 3 months old. I hang it from his bassinet, the toy bar on his stroller/car seat, and the toybar on his swing. It always catches his interest and as he's growing he's discovering new things about it. That the feet make sounds or feel crunchy, etc. It's great to watch him engage a toy like this. It's the first one that he had interest in, and the longest-lasting.
