Answer:
This kind of issues in growing children is very persistent. On joining school, they figure that staying at home was more fun and easy as compared to going school and taking classes. So they makeup excuses like feeling ill so they can miss school ans stay at home as long as possible.
In such a situation, parents should start with home tutoring. That way the child would be aware that home is going to be the same as school. It can also motivate children into going school and making new friends.
