Now children can go to kindergarten at the age of three or four. At this time, parents need to cultivate their children's ability to go to the toilet independently.

There are many children in the class, so it is impossible for the teacher to always check whether the children are wet and change diapers in time.

In fact, about 18 months, children can try not to wear diapers during the day, so that children can learn to tell their parents their needs.

The child is about two and a half years old and may try not to wear diapers at night.

Let the children learn to wipe their bottoms before they are three years old, so that they can solve their own needs in kindergarten.
