I always thought this was a myth, but now I believe. The terrible twos have hit us hard the last few days.

DD is doing a lot of whining, getting really frustrated when she doesn't have the words to tell us something or when she can't do something (because she physically can't or because we won't let her), telling us "no" all the time, and just plain ignoring what we say when she doesn't want to hear it! It's exhausting for us all!
Are you all going through this too? How do you deal with it?
Re: Terrible Twos
Yes! DD loves to say "no" - she will ask for something, I will repeat it back to her, saying like "You want some milk?", after she just asked for milk and she will say "no! no milk!" Drives me bonkers!
She's gotten a little better about whining, we try hard not to give her something if she's whining, she has to ask nicely and say "please" first.
It requires a lot of patience to deal with the terrible twos I think. I just try to ignore her when she's acting out and then reward her when she's behaving. It doesn't always work, but I try.
I am interested to hear what everyone else does though.

"Life is like a camera, just focus on what's important and capture the good times, develop from the negatives and if things don't work out, just take another shot."
I feel like DD went through this a bit early because she's easier to reason with now. She was about 18 months when we hit the no phase. Gotten better over the last couple of months which coincide with her being better able to use signs and words to communicate. We taught her sign language at 6 months. I am a big proponent and will use again.
When something needs to be done, eg return toy to shelf when we're at the store or stop shaking sippy cup because it spills the milk (this was a big one a few months ago!) etc, I tell her so in a very matter of factly tone. I also still sign to her now. I feel like the combination of both has more impact.
Be firm and direct. They can sense it if you're hesitant and will try to bend the rules if you let them.
Of course there were times when nothing I said mattered. Lots of patience and distraction worked.
Every now and then I used a non-vebal approach. I am still working on my poker face to communicate to her when I am really serious about what I'm telling her to do or not to do. They are so darn cute though. I know it isn't easy. Hang in there! It gets better!

We hit the terrible twos around 1 1/2 and it's finally starting to get better (knock on wood). Everything was a temper tantrum if she didn't get her way, hitting and kicking me, throwing food on the floor, and everything was "me do." After many, many timeouts (for hitting and kicking me) and lots of firm "no's" and standing our ground, plus an extended vocabulary, she is finally starting to listen and says "o'hay" without tantrums when we ask her to do things she doesn't want to do.
Yes it is exhausting. Her favorite word lately is mine and stop.
I really don't know how to deal with it I'm just trying to get through the day some days.
