3 year old attitude!

Oh, she just makes some days difficult. We went to Grandma's this afternoon, so before we leave I have her pick up Rylen's toys. Well she obviously knows that she didn't take them out so why the heck should she pick them up.
Me: Brit, can you please pick up RyRy's toys and put them in the bucket?
Her: Nope
Me: (firmly) Pick up those toys and put them in the bucket please!
Her: No, I'm not gonna do it. (she says this as calmly as can be)
Me: Pick up those toys or you're not getting your chocolate milk!
Her: UGH!
She walks over and picks up ONE F'N TOY, drops it in the bucket and walks away.
I made her pick up the rest of them too, but geezus she makes the simplest things so difficult sometimes. She challenges me, I can never just ask her to do something and have her actually do it without any attitude first. She'll yell at me, and flat out tell me no.
While it pisses me off, sometimes I have to laugh at it. She's still adorable, and makes my day interesting. She is stubborn just like someone I know....Aww just look at her....

Also, I found out the name of the congenital liver defect is that the gastro was telling me about.
It's Focal Nodular Hyperplasia or FNH. I'll be doing more googling tonight to see what it's all about.
