Hi, I've got 2.8 yo twins and I've noticed that for swimming classes, ski school, ballet etc, the earliest age for "unaccompanied" lessons (parent sits on the side/parent not present) is already 3. The thought that my two small bundles of chaos are going to transform into two reasonable children whom I can entrust to a swimming teacher for half an hour seems ridiculously optimistic. And yet I remember being 3, and my memory of that is that I was quite reasonable and could have gone at least in a dance class on my own.
So my question to you, dear mumsnetters, is: what age were your children when you felt able to let them go into an unaccompanied class or "sit on the side" and not have to intervene?
