Tantrum Break Down

I have been dying to be able to sleep in past 8am. With working or taking care of the house and family, I get really tired.

And with Skylee acting like a brat, isn't helping much at all.
Last night, I hit a new low.
We didn't leave the house to around 7pm to just run out and pick up a few things. Skylee fell asleep in the car and we woke her up to into the dollar store.
She throw fits over bears and balls. Then hubs gives me the money and leaves me alone with a cranky kid. While checking out I'm trying to put bags back into the cart, while she is screaming over a balloon.
I finally get her out with a color book and back into the car.
We stop by walmart for some over things and the tantrum level is building. She is right now a ticking time bomb of little girl tantrum.
I pick her up a hair brush, we lost hers and she hates mine so I give in. She hod the brush and starts trying to get the brush out of the packaging. I take the brush away and BOOOOOM! She explodes! Screaming at the top of her lungs and turning all red. We are in the brush area by ourselves or so I thought.
Here comes my low, wait for it ...
I raise my voice, okay I damn right yell at her,
" SHUT THE FUCK UP, I'M NOT DEALING WITH YOUR SHIT RIGHT NOW."
yep I said it.
And not only does it make you feel bad to lose your own temper at your darling little one (even when they're not so darling) is having someone see you do it.
As I'm saying this I'm coming around a corner to see this woman staring at me in horrible. You would have thought I just stab my daughter and this woman seen it.
At this point there's nothing I can do but keep walking with my head down.
I felt/feel so bad for acting that. I'm always seeing things like that myself in stores and saying I'm never going to do that. And last night I was that woman.
" Why do kids hate Walmart? Because every time you go in there you see some kid getting their ass beat"

The Terrible Two Hit Early

It came out of no where like a freak summer storm. The terrible tantrums, yelling, throwing herself on the floor and acting like we're killing her.
My daughter is 21 months old and is terrible twoing in the worst ways.
She throws things and hits people. She'll throw herself on the floor and screaming like a mad woman. She'll do it any where too. She doesn't care if people are watching or if where in a quit dinning area.
Are you eating without her? Oh no you didn't. Now she must throw a fit and try to grab your plate or whatever out of your hands.
We try everything to get her behave. We do the time outs in the corner. We take toys away. We say " NO NO if you do that the monster will eat you." Don't judge some fear is good for a child.
I'm running on a short leash and my nervous are shot. Some days I'm drinking a glass of wine at noon.
Sometimes she is the sweetest thing in the world. She'll give you hugs and kisses and laugh and lay on you. They next she's yelling in your face and hitting you.
I want my little sweet baby back. This monster that took of her body is driving me up the crazy tree. And this crazy tree is the fun kind.
How do you handle this crazy tantrums?
