I just read the first three pages of threads and this last one, so appologies for any repeats!
Toddlers group are not just for toddlers but as well for their parents who can be at times deprived of any other adult company.
Most parents /child minders who go to toddlers groups are quite sensible people, who do know what having little ones arround is like.
I do agree that hot drinks can be very dangerous, and that it is important to be carefull with them arround children, but it is also important to teach the children that they should not touch hot drinks, usually recognisable because they are in a cup rather than a plastic beaker or a glass.
It might sound silly but I think it is always better to teach a child about potential harm that can come to them than removing all potential danger. I think this is also true with other things like steps, cooking hoves, oven... IMO, parents need to be sensible in not putting the life or health of their DCs at risk, but over protecting them by removing every remote possibility of anything happening will probably get parents completely neurotic while their children are totally unaware that some things are indeed dangerous and will not be able to avoid them because they never had to "face" them.
It makes a lot of sense to me but I admit my long explanations can be a bit confusing sometimes so do not worry to much if you have not undrestood a thing!
