Oh you poor thing, it's awful when they do this isn't it? Funnily enough I was toying with the idea of starting the very same post this evening.
DD (4.1) had a complete and utter screaming, spitting, hitting, throwing meltdown about bubbles in the bath.
I tried to nip it in the bud by explaining calmly about the bubbles, giving her a choice of bath or no bath & bed and then counting to 3. She ignored me totally and went ballistic.
When she started to spit I just carried her into her bedroom and explained it wasn't on and that I'd come back when she calmed down.
After a few minutes I went back in, offered cuddles and we made up. She stayed in her room though and went to bed early (cuddling little miss trouble ).
It was all very confusing though, as she apparently had a sleep during the day so should be less tired than usual. I think it might be an adjustment to moving up a class at pre-school (start of new school year here).
I've seen her do it before, so I was a bit more prepared. The first time I ended up in a crying heap feeling a complete failure.
As everybody else says, I would get rid of the dummy. Dummy fairy was very effective here - posted all to fairy and a present was left behind. Take the first step! Then you can have meltdowns about bubbles instead
