I wish I had good advice! My boys always blame eachother. Maybe there is some one with a good answer cuz I'd love to hear it!
I agree with this and the age. My middle boys will blame my youngest..my oldest will blame everyone, it just happens. My oldest will now say,' I was only kidding' ..I say, 'no, that was not a joke, that was a lie'..trying to show him the difference. He will fess up a lot of times though as well. The others..it is just so difficult at times! I wish I had some advice, really.
