alt Hacker News> One study, for example, found that first-time mothers in Germany on average get an hour less of sleep per night in the first three months after their baby is born than they did pre-pregnancy. Fathers lose a third of an hour.
Yeah but how many times were they woken up in the night?
With a baby you might still get 8 hours total but you’re woken up 4 times a night which makes that sleep way less effective.
According to the article:
"It's not that modern parents are waking up more often. Work by Samson and others has found that people in hunter-gatherer societies usually wake more frequently through the night than we do."
But I think there's a difference between waking up at night because your baby is crying, calming them down, going back to sleep, etc etc. when you have a 9-to-5 job, versus if you're a hunter-gatherer.
