Mean mom....

So I'm starting to feel like a mean mom - am I doing something wrong or is it just kids being kids learning to express themselves? I'm hoping for the 'learning' part and not the 'I'm in the wrong' part.

Lea has learned that Mom is not always nice and sometimes she calls me "mean". Sorry - it's part of my job to ask you to work, help out and to tell you "No". We did stop the attitude of "I don't like you" and yes even "I hate you." Hate is now a 4-letter word in our house we no longer use and get busted when used. I'm guessing this came from school because it's not from home. She's learning to use words/expressions bigger than I think 6 year old's should know but it's fun to chat with her about her day.

Lucas today told me (while attempting to get him to take a nap - he did eventually take a nap) "I don't like you mommy." (to myself: Ouch, this is starting to hurt my feelings.)
Me: "Why Lucas?" (trying not to freak out.........breathe....breathe)
L: "Because.... I don't like girls."
Me: I'm a girl and a mommy.
L: No, your hair is down so you're a girl.
I put my hair up: So am I a boy now or a mommy?
L: A mommy.
Me: putting my hair up...mommy....down....girl.....then messy to become a monster and tickled him until he laughed so hard his face turned as red as his hair. :)

Are you a mean mom too? Do you make your kids work and be nice to others!? :)
