In addition to having adjustment problems dealing with a new baby.
He is also trying to do away with the nap.
And the kid has a mouth on him, which ain't helping. He's been snarky and bossy (right, like we take orders from him...) and outright unpleasant. He lost a nice trip to go see airplanes this weekend because I'd had it with him and so decided we'd take away a promised activity he was looking forward to.
Naps have been refused and played through and meanwhile we are finding him conked out under tables at odd hours. Apparently dining room floors are highly soothing to him.
