Hi,
I am a full-time working mum. My mum looks after my DS and I have paid for mum to take DS to Gymbaroo. My mum loves taking him, as it gives her something to do with him. It is not all that much more that our local gym's kindy-gym. The time is divided into free-time and mat time. Apparently, DS loves free time, but does not always behave during mat time. As I am not there, I don't really know the details. I think the group time and socialisation is great.
