I was just reading a post of yours and thinking you should change it!
I don't like any that have been suggested! There's lots of mum2be's and the like and if you go for soon2bemrsgardner then you'll just have to change it again.
You'll probably hate this, but how about SALLY? (Sam, Alice & Lewis LY)
Or something that's just you and doesn't include children's names - something you are into/like etc.
