Bathsheba I think you're right. I'm pretty sure OH&S would have something to say about all these places that have child carers, who are waltzing around with hot drinks.
My DD has been going to childcare for about a year now and I go in and drop her off and pick her up at all different times.. I have NEVER seen them with a mug or anything hot.
Even for the Mother's Day after tea, there was NO tea. Nothing that was hot and spillable.
I think it's fair enough too.

Umm.. i believe that's what a "tea break" is for.

Linda, I understand your concern (they may not drink coffee, but I did have a smoking issue at our kinder not too long ago ). Anyway, i made it clear to the Director that i didn't want the particular staff member to be told who had brought the issue up. And i sa her run into the room as soon as i went out to the car. I couldn't wait to go pick DD up that afternoon. For the first time ever, DD was extremely upset. I asked her in the car what wa wrong and a a 3.5 yo DD said she was told off by S***** because I told her that DD had said she saw her smoking. Apparently she ws also excluded from activities. Well that was enough set me ablaze. I rang the director as soon as i got home and told her how disappointed I was in the way she handled the situation. she lied and said she didn't say anything, but then had to let it slide, because how else would DD know i brought it to their attention if they didn't confront her.
I told her that nobody had a right to question my child without either of her parents present.
I think she knew that if i was doing to cause a problem for them, i was well aware of where to go and what to do. All i wanted was to bring to their attention that there is a problem and they need to change the way they behave in front of the children.

In short, there is nothing more valuable to us than our little ones. Anyone who is responsible for looking after them and doesn't do so, needs to be pulled up on it.
Don't feel bad. You are a normal *caring* mother!
