I love this turtle & so do both my daughters (1 year & 4 years). As much as toys that make noise are fun & entertaining for them, it's great to have found a quiet toy they can both enjoy! I had actually thought there was some sound to it when I bought it, and was surprised it didn't, and worried my girls wouldn't like it because of no sounds, but they didn't even seem to notice the lack of sound. My 1 year old is still trying to figure out how to stack them, but my 4 year old has fun helping her learn to stack. My 1 year old has no issues putting the stackers into the openings, then my 4 year old opens it for her to take them all out & start all over again. I highly recommend this for any parent looking for a quieter toy!
