Help! My sweet 5yo dd has undergone a change since starting Kindergarten. She was always very well behaved: even though she is strong-willed, she has never deliberately acted out. At Kindergarten, which she loves, she is fine. But at home, she has started becoming difficult. She interrupts us, either with words or with loud noises. While someone is talking to her, she starts making sounds. She yells and occasionally plays aggressively.
I am guessing this might have something to do with either seeing other kids behaving this way and trying it out (she has done this in the past). Or needing to let out all of her pent-up energy after behaving so well all day (full days of K) and following rules, reacting to bells ringing, lining up, etc. (all of this is new for her). Clearly she feels safe to let it all out at home and I'm glad of that. But she is becoming difficult to handle and I am worrying that we need to give her some firmer behavioral boundaries.
First: what's this really about? I need your wisdom here.
Second: how shall we handle it? So far, we've tried talking to her rationally (when she does not interrupt) and explaining that we understand she is needing to explore these behaviors, but that we have to figure out a way she can do it through play rather than all the time with us. We've tried withdrawing when she interrupts (stopping what we're saying and telling her why we're doing it). We've tried letting her know that we're beginning to get angry and reminding her that everyone gets upset when that happens. But I am really at sea here!
Any advice for us? Thanks.
