The obstetrician was the one who told us to check whether Linnea was a boy or a girl - Rob and I were busy touching her as she lay on me and saying "That's my baby, do you see my baby?!" and so on. It took Rob several hours before he changed from "it" to "she" when referring to her; I changed almost immediately.

"When I was born, they looked at me and said What a good boy what a smart boy what a strong boy. And when you were born, they looked at you and said What a good girl what a smart girl what a pretty girl." - Bare Naked Ladies

(And re the nursery rhyme - it could easily have been a rhyme with a girl in rather than a rhyme with a boy in, you're right.)
