Q: My one-year-old has played with this toy for several months. He disregards the keys and pulls up on the lids themselves. Not quite what I expected. He's had more fun pulling the lids up and pushing them down again, and only accidentally happens upon the moving keys and the noises they make. The sounds alternate between giggles with music background and animal noises, also not quite what I expected. But it's noise I can deal with. The volume can be adjusted or turned off (through I myself can't distinguish between "soft" and "loud" on this thing). My son enjoys the toy, but it may be of limited or intermittent interest.
A:
Positive
