The cause today was me getting her out of the car when we got home from being out

We tried calm. Talked to her. Tried angry. Tried time out. Tried leaving her alone. Finally calm again and she started to wind down.

It doesn't seem to be an attention thing - she's getting stacks of one on one time with both DH and myself and I'm able to play with her far more than I was able to while pregnant. She'll argue everything until she's black and blue ("Do you want to go outside?"; "NO!" ;"Will we stay inside then?"; "NO!"). This is the third tantrum like this in two weeks. First one was for no apparent reason, second was hair washing day which has always been a challenge (she has afro-style curls) and then today.
