i'm so sick of noise! dd1 (who's in her terrible 2s) has not adjusted well to her little sister's arrival and competes for attention by yelling when dd2 so much as whimpers. It's now become an automatic reaction and I can't take the yelling/crying from both girls. I've tried 1) explaining to dd1 that baby is crying because she's hungry/tired etc and dd1 shouldn't worry, 2) ignoring, 3) sending her for 'time out' in another room each time she yells for no reason. none of this is working. dd2 is 8 months now and dd1 seems to have got louder in her yelling. anyone else have this problem? any advice is appreciated!
