I am reading a booking titled "Your Three Year Old...Friend or Enemy" by Louise Bates Ames that my therapist recommended. Yes, therapist...that's how nuts I am with my 3 year old and 18 month old. By page 4, it described my son to a t and by page 7 I was feeling 100% better that he is totally normal. Basically, there are stages of equilibrium followed by disequillibrium which is what your daughter is in. Seems to go in 6 month increments. Our son just turned 3 last month but he is already showing behavior of three and a half. Check out her books...she has them for each year and will make you feel tons better that your daughter is going through the normal growth phases. Good luck and we will get through this!
