hey :)
My daughter, who just turned 3, will do the samething. With her it really depends on her mood for the day on what does and doesnt work.
I'll try to calm her down, all the stuff that you mention, sometimes it works and sometimes it doesnt. On the days that NOTHING works, I just put her to bed. I just simply tell her how it is. 'you want to throw a fit you can go lay down. Maybe youll feel better later.' She'll have a fit aobut it and I'll just talk to her clamly saying something like "I know you're cranky today. It's ok, everybody gets cranky sometimes but it's not ok to have a fit." And then I just tuck her in the way I normally would.
Sometimes she'll crash right out! Other times she'll fuss or cry for a few mins before going to sleep. And almost always, she's much happier after a nap. There are a few days when she's up at 7:30 and back in bed as soon as 9! I think that days like that, odds are she didn't sleep very well at all.
She just turned 3 a couple of weeks ago and already understands when I say, "you can stop your fit, or you can go lay down. What do you want to do?" She usually stops.
I think her fits are slowly starting to decrease. Hopefuly you son's will start to decrese soon too!
Good luck!
