Looking for some advise please.
My 11yo son has me at my wits ends. He constantly lies, sneaks money out to the house to go to the shops before and after school, he gets angry easily especially with his computer games. Earlier this week he was pretending to be ill to stay off school. Monday and tuesday i received calls from the school and told them he was fine and not to send him home. Wednesday he woke up going crazy saying he was really ill, i didn't care etc. So i kept him off for the day more due to the fact her was making the rest of the family late. He admitted he lied, he wasn't ill but had fell out with some friends. I have taken all privileges away. Desserts, computer games, tv time and gave hin extra chores. However today he has lied again about taking money to buy food ( he had breakfast he has his lunch not like he ia hungry).
Any advise on what else i can do to get the the bottom of the lies?
