My 6yr old son got in trouble at school yesterday. He lost his temper and squished a girl's finger with a cup on the work table. I was horrified that he hurt another child and embarrassed about his behavior. Thankfully his teacher called me from school, so I had a few hours to think about an effective discipline tool.
After talking through the situation and determining a better course of action for future interactions, I told my son that he needed to write an apology letter to the girl and the teacher (long tedious work for a kindergartner, but he's capable of it). His other consequence was no TV or computer for the whole day (a definite favorite of his).
But I struggled to know what was appropriate. At home discipline is easier, because it's immediate. But disciplining 5 hours after the incident is much more complicated. If anyone has ideas, I'd love to hear them!
