Big DD keeps shrieking around little DD. It makes little DD cry. We've tried all the things that usually work (usually just an explanation about why a certain behavior is bad is sufficient) but she keeps screaming. The only thing that stops it is to tell her I have to leave with baby if she continues. She continues. I go to the bedroom. She sobs outside the door, but she stops. It's not what I want to do, and feels a lot like love withdrawal to me. (We practice Unconditional Parenting, meaning we don't do punitive punishments but work together for a better understanding of issues, in a nutshell.) But what else can I do? We talk about it after, and she says she understands that it hurts baby's ears and she likes baby and doesn't want to hurt her ears and blah blah blah but she's right back to it in a day or so. Ahhhhhh! It's not really like her to continue willfully and knowingly hurting someone else, especially baby sister who she adores beyond belief.
Re: 3 year old screaming around baby
All that is to say that it seems like the natural, logical consequence of screaming around her family. Her family doesn't like it and it hurts their ears. If she can't stop, they'll go to another room. As long as she understands it as a natural consequence and not a punishment, and she is secure in your love for her, I wouldn't worry too much.
Sounds like you're doing what is most effective and makes the most sense to her!
So maybe the act of removing yourself from the room with the screaming toddler is enough to let her know you and baby don't like it and it won't be tolerated...so you don't have to leave her out there for a few minutes, but maybe just a few seconds. Just a thought! And what works probably all changes as they get older so I'm just sharing my experience.
I always remind DH that we want to model the behavior we expect from DS. If we don't want him to scream, we shouldn't scream. If we don't want him to leave his toys all over the place, we should make an effort to put away things we use when we're done with them. If we want him to grow up turning off lights when he leaves a room, brushing his teeth in the morning and before bed, and putting his clothes in the hamper when he takes them off at night, we should be doing all of those things!
More Green For Less Green
I understand the negative attention problem, but if screaming is attention related, anticipating that need and working to figure out at what times the child feels she needs more attention (i.e. if it's while mama nurses the baby) and seeking a way to meet that need (maybe singing songs with her or a simple game: asking her to find and show her certain colored or textured ("find me a soft toy, a round toy, a hard toy, a striped toy) toys or pieces of a puzzle, etc.) would be better than ignoring the behavior.
