Why didn't she want to draw in the middle? This is because she is not interested in painting. If she is interested, I believe the child will keep drawing. If you insist on learning things that you are not interested in, this behavior is harmful to children. You should respect your child and ask her if she wants to learn.
If she is interested, but still can't hold on and is easily distracted, well, she is only allowed to draw for ten minutes every day. If she wants to play after this time, she won't be allowed to play, and no matter how much she asks, let her know how to cherish it.
In addition, buy less toys for your child, take him out for a walk more and communicate with him more, so that your child will form a good habit of cherishing things and have a particularly harmonious relationship with you.
