I have two girls just about the same age just a few months younger and the same happens for me. I think it is the age mainly because my oldest does the same thing. I have to say it is probably a little jealousy as well as she is probably trying to see exactly what her boundries are and how far she can push you. Seeing as you just moved that maybe playing a big factor in the situation as well. My husband and I just moved 3 months ago and we had a terrible time with my almost 5 year old. I have tried taking things away and it didn't work for my daughter. I give her a time out for 5 minutes and then we discuss what she is doing wrong. I have also started using a responsibility chart which is also helping. You may want to try it out because then you can reward them after each day with stickers or something little or even at the end of the week go for ice cream if she behaves ect. Just a few ideas. It is a tough age and unfortunately these little ones don't come with manuals. ;)
