Thanks very much, everyone. As I said, I am sure it is just bothering me more lately because I have been very run-down and lower on patience than usual.
I know that he is just pushing all his boundaries. I am continually reminding him of our expectations, and I know that it will all come together eventually. Too bad I am starting a month of mat leave soon... I know that I will have to retrain all the kids when they come back, SIGH.
I think I will try that tactic of saying in front of mom "_______, we LISTEN to mommy please." Nice and firm, but kind. Perhaps she will see that it's something that can be worked on, not just a phase to get through.
PS> I know it's not "just me" as my mom was over today and busted a gut laughing at his antics today. All she could say was "better you than me!!".
