pregnancy #3

I got pregnant with Kate when Zachary was 15 months old.  Kate is coming up on 15 months and I keep looking at her unable to imagine how I felt that Zachary was old enough to start on another child.  Kate just seems so young.  She is still my baby.  How did I feel so ready to be pregnant again when Zachary was so young?
I find myself thinking that this time feels different and I don't feel quite ready yet.
And then I look down and see my big belly and remember that I am already six months pregnant.
Well so much for that.
