I didn't know about your child's illness. Can your child go to an ordinary kindergarten? Although he is like this now, if he is in an ordinary kindergarten, he is likely to have an accident in ordinary outdoor activities. As the mother of the child, you should take more pains. If possible, be a full-time mother and take the children to kindergartens or early education institutions that only attend for half a day, so that the children can keep healthy without leaving the society.
I remember a classmate in primary school also had a heart attack. He usually has nothing to do in class, but he can't go to physical education class.
