Thanks Kim, its actually my real nickname!!! long story how I got it, but needless to say, it was my partner that came up with it!
Also, I know I might get my ass kicked for saying this, but if your children are old enough, it might be worthwhile explaining to them (in a censored version) why some things affect you the way they do, or what are certain triggers for you.
I have only just gone 22, but my memory is unfortunately crystal clear back to the age of 2, and as a child I remember my mother occasionally opening up to me, or me figuring things out and trying to help her with them, in the times when I wasn't being a little shite!
My mum went through some pretty horrible things as a young girl, I'm not at liberty to divulge, but when I learned about them when I was a child, it helped me understand her, and why she sometimes acted the way she did.
Anyway, just food for thought, I'll definitely understand if you balk at that idea, but my thinking is that your children are usually the closest to you, and they can become your best friends as well as your children, if you let them, like I am now with my mum.
