This two hours, this is when he gets up with the kids so you can have a Sunday lie-in, yes?
And the rest of the weekend, you're out as a family playing tennis and whatnot.
I'm a pretty AP sort of parent, I second guess myself constantly about how much attention and love my DD needs (a LOT and it never seems enough), I don't believe in turning on the TV or the laptop until she's in bed except for her alllotted TV time. And I still think that a 6 year old who is going on about skinned knees so much that the whole family has to leave a game, and is still going on about it at bathtime (which, I notice, you and DH do together) needs a bit of bucking up.
I think that your response to your DH's parenting has been to overcompensate, frankly. You clearly think you are right and he is wrong in absolute terms. You keep pulling him up about it. You've asked on another thread how to find an independent expert to tell your DH he is wrong.
I wouldn't be surprised at all if your son has picked up on this and is playing you two off - crying to you about his Dad ignoring him because he read the paper, I know it seems heartbreaking but what I get from it is that your son has figured out that it puts you on his side against his Dad.
You need to back off and consider that there is a middle ground between your DH's style and yours, because as long as you think that you are the Right And Righteous Parent, which is absolutely how you're coming across, it's not going to get solved.
