Two, one in class (organizing teaching) and the other in class (in class, responsible for discipline, reminding children with inattention, helping to distribute materials, distributing teaching toys, etc.)

It should be noted that early education centers and kindergartens/nurseries

The difference is that early education only provides educational consulting services, that is, only classes are held, parents wait outside, and they are not responsible for child care (children eat and drink Lazar), so there is no such thing as a wet nurse.
