Doing new things everyday

Shes so cute sometimes, Lately she has been obsessed with getting her picture taken...
I wonder what could have made her that way....? :]
Maybe the camera that has been non-stop in her face since she exited the womb. lol
Lately she has been sneaking to get my camera out the diaper bag and turning it on and holding it above her head pointed at her.
When she does this, she doesnt completely get how to take the picture.
She knows what button to push but she holds it down instead of just pushing it.
So she sits there with it pointed at her saying "cheese" "cheese".
She is so conceited too, she loves to look at herself and everytime I take a picture of her, she says "see".
She wants to look at herself as often as she can, and when she does see the picture of herself, she says "aw" or "pretty".
She occassionally likes to pretend like shes taking pictures of mommy and daddy.

Also on the topic of her being conceited.... Everytime she puts clothes on that she thinks is cute or gets a bow in her hair or anything like that, she says "mirror" and runs into our room to look at herself in the mirror.
She is too cute sometimes. :]

Another new thing for her is when she is pooping in her diaper, she feels the need to run and hide.
I dont know what could have given her the idea that this is embarassing, we have never made her feel bad about doing it?
She has this one particular wall in our apartment that she runs behind and stands there until she is done.
When she is done, she comes to us and says "poopie".
If she cant leave the room she will just go to a corner and cover her face.
I really dont know how she picked this one up.

About a week and a half ago we took Rylee to JCPenney portrait studio to get her christmas pictures done and while we were waiting for it to be our turn we were sitting out in the little waiting area.
Well they have toys there to keep babies occupied.
And there was a little girl waiting with her mom too, I would say the little girl was about 3?
And she was playing with a toy and Rylee came up to her and started playing with the toy with her, didnt even try to take it away from her.
And the girl says "mine!" and takes the toy away.
Well ever since that day, Rylee has loved the word mine, and I hate it soooo much.
I want her to be a brat. And she completely gets how to use it. I dont know how hearing it one time has taught her to keep using the word over and over again.
Every time she says it she gets popped and I tell her we dont say mine.
But its an every day thing.
She takes toys from Lexie now and says it, or takes the phone from me or jake and says it.
I have to put a stop to it, I am not going to have a little brat on my hands.
