Thank you both. 2muchcoffee, I do the same with my son. He has to earn computer time, and he only gets to play computer or videogames on the weekends period. Losing priviledges throws him into total meltdowns, every time.
The problem is that he won't take responsibility for his actions. It's always everybody else's fault. Like today, he did not get to play on the computer, so he threw a major fit and blamed it all on me, saying that it's my choice and him not getting to play is all my fault.
