Mother goose kista - ngn med erfarenheter/åsikter?

I have two kids and both of them have gone to Mother Goose Gärdet, which is an excellent pre-school.  They both learned to read there when they were only 4 years. Since we have moved, our youngest daughter is on a waiting list to Mother Goose Kista.  My work mates have their kids there and they love it.
