We have bought the whole series. They are very nice music books. The only downside is that they are a bit expensive, especially their batteries.

Apart from the fact that the pages are very thin, we love it. It was the first book I bought for my son when he was born, as I am a fan of the genre. Until today, at 15 months old, it remains his favorite.

The series is commendable, and if your child listens to music and reads, it is a must. I am not a fan of the genre to judge the songs
