Owls. Fruit bats. Vampires. Pregnant women.

What do these creatures have in common? None of them sleep well at night and, in the case of pregnant women, neither do their partners.

A pea-sized bladder, sore back, indigestion, swollen ankles and tender breasts are ingredients in the uncomfortable cocktail that makes pregnant women sleep poorly. They all add up to interrupted sleep on the part of the pregnant woman and, by proxy, the expectant father will not sleep well either. Dads-to-be should make sure that in the months prior to the birth they eat a balanced diet and try to maintain a regular sleep schedule so they are not completely fatigued and unhealthy before the little one arrives.

This may be nature's way of preparing the new parent for many sleepless nights ahead. I would however much prefer being woken by my new, adorable (as he will of course be) son than by my wife's huffing and puffing as she struggles to roll out of bed. I'm actually looking forward to being woken by the little one, for now it's the wife that's driving me to exhaustion.
