We dont do anything structured other than MG every fortnight.
I try and get her out doing all the "balanced" stuff every week though.
So in the last week she has had music morning, drawing morning, playing in the park x 2, visiting family morning, and morning tea out, plus playing with kids. Other things I mix into it are swimming with dad in our pool at home, morning bathies with mum, outdoor play, animal play, reading and I want to start going to the reading time at the library.
I would love to go to something structured, but I dont know how much she will get out of it when I know its stuff I can do at home wiht her? Sure its good for the interaction, but she loves being with other kids in the park.

I think the only thing I am really missing out on is interaction with other kids. Is that really worth $100-$200 a term??
