I go to a thing called mainly music which is run by the salvation army its really really good.

Music program then the kids have morning tea which is supplied then they play/have art in a fenced off area while the mums have morning tea which is also supplied, all up goes for 1.5hrs and is $4 per family no matter how many children you have

A few of the songs are a little religious, but mild so just depends if this would be ok for you...

for example one of the songs goes through all different parts of the body with actions, like we are waving to our friends and we thank you God for hands etc etc
