Baby Einstein - Baby Mozart - Music FestivalBaby Einstein - Baby Mozart - Music Festival by Disney

I'm just listing one.  But VanGogh,  Bach, Mozart, Numbers Nursery, McDonald and Beethoven are the ones he likes best.  Although, if your baby dislikes these, Baby Wordsworth is unlike the others.

We have most of these. Much better for baby than Baby Einstein.  Right and Left Brains are just great.  He also loves laugh and learn, peek-a-boo and jingle bells.
