I have sent my 2 year old boy there for a month by now. He goes there twice a week. Being used to playgroups, he had an attachement issue at first, he couldn't get use to not having anyone accompanying him in the classrrom, but he is adapting quite well. He learned quite a lot there. In just a month, he mastered a number of activites including the transfer cotton ball activity, fitting various cylinders into the right holes of the blocks. He had so much fun last week help building and walking into the maze with the red stairs / red rods. I am quite satisfied with them.
The only thing is my son has two teachers for the weekday class and for Saturday. Although they are both very qualified teachers, and they have lesson plan and a indiviudual file for my son, I wish they could be the same person. I took some time to talk to their Saturday teacher. She got her degree from England. She is very sweet and she explains lots of thing to me in details.
For those who believe in the Montessori system probably think that a couple of hours a week is not enough, but hey, it is better than none.
