My one year old is starting to give me and her daddy attitude. Yeah we are going to snap her out of this screaming at us thinking she's the boss and owns everything real quick. She gets everything she needs and most things she wants no need for her to be acting like a brat. I don't know if it's daycare that's changing her attitude or she's just going through a phase trying to see how much she can get away with. She will find out real soon her little butt will not be acting this way with us. Her attitude has changed this past week and me and her daddy have no idea what is going on with her all we know is one week of her acting like little miss diva is not okay with us.
