We bought these for our nine month old and she's been playing with them multiple times a day for the past five months. We keep them in their bag and it's always an event to get them out in the morning. We hide them (in plain sight) around the living room and ask her where the monkeys are and she goes and finds them. She likes tossing them and holding them during walks (haven't lost one yet). She's very into multiples of the same thing right now, so these are great. We also have the ikea finger puppets, but they're smaller and less substantial and she hardly ever touched them. We don't use the monkeys as puppets or with the book/song yet. But we haven't had trouble fitting fingers into the puppets either. Though, I have smallish fingers.
