Our oldest son is 5yrs, and still reminds us to turn it on at bedtime. And if he awakens during the night he will go turn it on again. We have 3 kids and they all love it. One night they weren't able to listen to it because it accidentally got broken. They've all listened to it since they were born. But our 5yr old decided that night he could sing it to his 3yr. old brother and 2yr. old sister. I heard him on the baby monitor and it was so heartwarming!! I promised him I'd replace it soon and he hasn't forgotten that!
