Do they have the staff to be able to do that? My son was in a pre school nursery with over 20 children. They didn't have enough staff to take 20 kids to the toilet.
The school nursery I sent my DD to expected them to be toilet trained and wouldn't help them with toileting at all. Have you asked them what their rules and procedures are in regard to this?
Surely they can't do that for every child, he needs to practice himself.
It's not really their job when they have so many, it's usually send them off on their own, watch them in and out.
Ive only read part of the thread so far and I'm sure there are more comments similar to the ones I have picked out above.
Any person who works with children should support them in every stage of their development. Not having enough staff, not being 'allowed' to and 'it's not my job' are not valid excuses and any person using such lines as an excuse should not be working with children.
Nor should any person who doesn't understand that all 3 yr olds are not the same.
Working in a childcare setting means that you help, support and educate every child in every stage of their development. That is your job. That is why you are there. I despair sometimes of the expectations we place on small children, no wonder we have an increasing amount of them with anxiety.
