I agreed with dh I would seek some MN wisdom on this.
Ds is 8, nearly 9. He isn't a natural approval-seeker, so he's not super-instinctively-obedient, but he is good with me - just about always - I would describe him as "compliant", with me. But he is being thoroughly unco-operative with dh (and, at the moment, with his teachers, which is a long-standing separate issue) - it's as if he's one of those dogs which recognise only one authority.
Does anyone else have this situation, and if so, what helped?
(By the way, this won't be because I am a SAHM and as a result dh doesn't "feature" in the parenting - dh and I both work full-time, so we both have the same sort of level of parenting input.)
