If you want to get your little ones learning Spanish at home, this is an easy book with CD that might be good. I have used it with little early learners and they love the songs and the exercises. I was even preparing little dancing moves to go with the songs and the children loved to join in.
It has a little bite of everything, from learning animals names, colours, clothing, body parts… It is very colorful and it has some nice stickers too. The little ones always love stickers!
