Danny I am right there with you!  Kaity will be six in January as well, and as I describe it to others I SWEAR she PMS’s 27 days a month.  I cannot tell you how many times I tip toe around her moods.  If I say one thing to upset her, she is mad for an hour.  This is especially hard since I have 8 and 9 year old boys, both non-cah, and they see what goes on.  They give in to her more often than not, and it amazes me at how readily they do it!  They have developed the patience of Saints and I am proud of them for it!  I keep hoping the assertiveness in her will settle down a little as she gets older.....here’s to hoping!
