I don't think you are expecting too much. The playgroup i take my two to - they have play time and there are usually different toys out every week but the one that is always out is the play dough lol. Then they have morning tea and mums usually have a coffee and some cake/biscuits whatever is brought in, then it is craft time then after that it is singing time and then story time although we do usually go over the time.

I would look around for another playgroup - i joined mine through playgroupnsw.
