Ask the professionals....anyone?

Hello lovelies! Well I thought it was a while since I posed a life altering question so when better than a Friday night!

I was just wondering if anyone has had experience with Montessori education? As you know the Madam is three and an energetic, inquisitive bundle of three she is. We have a local Montessori school that a few kids from playgroup go too and it sounds like it may be beneficial in keeping her stimulated. I am also hoping to find a way of her being a bit more 'social' with other kids as she prefers adults most of the time - I am thinking that's an only child thing?

Anyway any advice, as always, will be much appreciated xx
