In recent years (and before getting my eggo preggo), I've had a few dreams about having a baby (once, the baby was a spoon, but that's neither here nor there). In 100% of the cases, the baby was a boy.
When I became pregnant, I had no dreams about babies.
Then I had an ultrasound, and wouldn't you know it? The baby is a boy.
About once a week now I have a dream about having a baby (preoccupied much?). I can never remember anything about labor and usually forget changing baby's diaper (motherhood anxiety?), but these days, the baby is always an adorable little girl.
