DS just turned 5 is doing exactly all these things. Defiance and rage is enormous. I'm a total devotee of how to talk so kids will listen and listen so kids will talk. Can't recommend it highly enough.
123 Magic sounds good too, will add that to m library!
Things that get DS are - Unfairness, me being cross when to him it doesn't make sense or doesn't feel fair; embarrasment, embarassment; not getting his own way.
For the latter much of it is my fault. It's been the holidays and we went away for two weeks too and the rules have been totally up in the air. Total inconsistency so he's trying it on because all normal rules have been very flexible. Our first week back properly at home, just me and him is transofrming things.
OP - In the example you gave about the balloon, how to talk book would say firstly name the feeling. He was really shocked, suprised, frightened and massively disappointed that the balloon popped. You deal with those emotions first and don't ever, ever utter the words never mind! So you do a oh my god, what a shock, that really surprised me, that was so loud. You loved that balloon didn't you and must be very unhappy it burst. You looked after it all that time safely in your room. Then you move on from there.
The thing you did, which I totally did in a similar row the other day with my own DS, is the original upset got mixed up in subsequent issues. I'm afraid ours was in the park, and when he was already upset about one thing and after warning him 4 times I picked him up and took him home. He screamed, for the first time ever, I hate you I hate you I hate you all the way home in the car. It took us about an hour to get back to normal. He told me, the whole thing was my fault and that he was so furious this time because the whole thing had been unfair.
and I'd made it way worse. He'd also been embarrassed by original incident and then me taking him away in the park. It was horrible for both of us. However, I did "win" the battle in the end, however unfair, by picking him up and taking him home. Four days ago now and things have improved immeasurably. It's all still going on, but the edge has gone, which is helping me use the how to talk tactics, which in turn is making things more manageable.
Great to be reminded about the testosterone surge. I'd forgotten that and it helps remind me it's a stage and not all my fault. Also huge reliefe to hear I'm not alone!
