I am in need of

some help. I am VERY frustrated right now and I do not know what to do!! Katie has been VERY FRUSTRATING and I have no clue how to go about changing things. She hardly ever listens to me. Gets into things over and over again. And just will not leave her sister alone and she has this thing of now going into her room and waking her up. Which was kind of fine two weeks ago but now Emmy is in a big girl bed so here they both come into my room at 630 in the morning. Then Emmy is very grouchy and won't go back to sleep. Then to top it all off I feel she is not getting enough sleep so that is making her grouchy on top of it all. She talks back. She sounds like a 13 year old sometimes. I am sorry I keep rambling. I am just at a very aggravated point right now. I have tried time outs, taking stuff away. I am just at a loss right now!! Any suggestions?? I know a lot of it has to be because she is 3 and it is the age but this bad!!??!!??
