My daughter who will be three next week will not stop arguing with me. It is compulsive, passionate, and frustrating for both of us. I am a single mom and a preschool teacher. I have to make a conscience effort not to argue back with her. She will argue about such simple things: that's not an apple, it's an orange (no really it's an apple): it's sunday!!!! (no, pretty sure I'm the one who can read the calendar and it really is monday, now put on your shoes we have to go to school). It has been going on for about 9 months now. She started talking in complete understandable sentances at about 16 months old. She is bright and cute, and knows it unfortunatly. She is the light of my life, but she is driving me crazy. I do understand three year old behavior, I have a BA in ECD, and what she is expressing is excessive and uncomparable to children her age.
