My eldest is 9.5, and in the past few months we've seen a dramatic decline in his behavior. He has always been quiet and sensitive, and until very recently he was very kind and empathetic to his younger siblings, respectful to his parents, a good and motivated student... basically an all-round 'good' and easy kid to parent.
I don't know if it's the age or something else, but recently he's been testing boundaries multiple times a day, being unkind to his siblings, taking things without asking (then lying about it... he was always incapable of lying before!) Honestly, I'm any my wits' end. I try to give him 'special time' and he gets so many fun activities and privileges. I lie with him in bed and ask him if anything is going on at school, but all I can glean is that he doesn't like his teacher this year (his best friend also left the school, but they still see each other regularly, and he has other friends) but the behaviour shift happened towards the end of third grade, when he had a teacher he loved.
My husband thinks that DS is acting spoiled and entitled, and has already threatened to cancel our planned Thanksgiving break as traveling with DS while he's talking back, whining and being mean to the siblings just ruins it for all of us. There have been no major 'events' in DS's life that would explain the behavior change. Please help! I want my sweet son back!
