My son has had his first Christmas he was 9 months. He once A-DO-ER !!! It has prompted many to move and dance like this little dog. The songs are super catchy and joyful. It also'm having this little dog !!! Today my son is 21 months and restarts it when it's still fun. I highly recommend it is a small very cheerful and entertaining dog that encourages baby to move by imitating !! The only downside to explain the 4/5: engine noise but does not cover all the same songs as I could read it. Get used to it, but it is true that at first we thought it was a little too 'strong'
