oh man, the screaming! I'd forgotten about that! My last must be about to hit that stage ... amazing how thoroughly I can release unpleasant remembrances ;).
Yep, all three older kids hit a stage around 2 when they discovered
(1) they *could* scream (very exciting, just on an experiential level) and
(2) screaming *really* gets some interesting reactions, which makes it interesting as a relationship-tester as well.
ARGH, says mommy.
I used a two-pronged approach: defining when screaming was not acceptable (near people, in small enclosed rooms, after bedtime, anywhere in public unless someone was trying to hurt or steal you) and when and where it was (basement or upstairs, if noone else was there) ... and then moving the child to the "ok to scream place" and leaving them there (no significant emotional reward of a mommy reaction), or whatever else was a current pertinent consequence (we can't stay at the restaurant, if it's a place they like; the kid loses treats for the rest of the day or whatever is high stakes for that kid, if they are trying to force the family to leave somewhere and shouldn't be rewarded by the family actually leaving).
And partly, I just didn't care. For at least one of the kids, the rules applied when Daddy was home (because he couldn't handle the noise), but not when he was gone ...
And yeah, I agree with the other mom, it is about three months. Like all other things that seem like they will never end, it will end :).
