My son suddenly started refusing to go to school.
My son is 3 year and 4 months old. We put him in school 4 months ago (4 hours playgroup). Last month my wife had to spend a week in the hospital due to some problem and my son became quite sensitive but went to school normally. Last week, I had a mild accident where windscreen of my car was cracked. My son was with me at that time. Since then, he refuses to go school. It's not only at the time of going school but at home he keeps crying the whole day that I would never go to school. We can't understand the sudden change. We have talked to his teacher too and she says he has also started crying at school. However, they are sure there is nothing at school that could have caused this.
Can someone help me to understand what could be causing it and how I and my wife can help him to get normal?
