The child walked for half a year, they threw away a lot of money. In the end, the child could not even name 3 words all the time, some songs on the disc, rhymes - and that's it! We hired a tutor - in a month!!!!! the child knew elementary phrases about himself, his family, and the names of flowers. animals, toys! If you want real knowledge, you can't go far on fairy tales and songs alone! I strongly advise against it!!!
