Terrible 2's

We have already hit them. Jacob has these awful streaks and is horrible!! We will be in a store and he will just hit me and scream and run away from me. He came up to me yesterday with an open pen, I followed him and he showed me his newest art work. He scribbled all over our wall in my bedroom! At least it is on ugly wallpaper that we plan to take down! He also drew us a lovely picture on our kitchen countertop with permenant marker! Luckily, I have a husband who knows how to fix everything and got it off when I couldn't. He tells me NO! That is all he says. If I tell him to come here, he comes up to me, while rolling his eyes, and says "What?" In a voice that is kind of like, I'm annoyed by you but I'll listen. He isn't even 2 yet! Where does he learn this?? Is there any way to lessen the terrible part of 2 year olds?? Luckily, he's pretty good most of the time and such a sweetheart. Loves to give kisses and hugs. What a cutie!
