Any new mum will tell you, one of the trickiest things about parenthood is the whole sleep thing.
AKA, they get zilch, whilst their red-faced baby is having none of it either.
"Oh, remember the days when I used to sleep in till noon on the weekend!" you quietly whisper to yourself on the night feed, trying to ignore the fact it's 4am.
Well, it may not be all bad, as scientists reckon that babies crying throughout the night is a good sign and it can actually mean higher intelligence.
According to research from the University of Bristol, not sleeping through the night and high levels of intellectual achievement might, in fact, be correlated.
Professor Peter Fleming who's worked tirelessly on the research told Buzzfeed:
"Human infants are not designed to sleep for long periods. It's not good for them and there is absolutely no evidence whatsoever that there is any benefit to anybody from having a child that sleeps longer and consistently."
"That's not perhaps what most parents would like to hear."
He also adds that babies tend to sleep during the day and 6pm to midnight is the time "they're going to want to be awake the most".
He continued: "Biologically that's a big advantage because they will have more attention from their two primary caregivers at that time of day than at any other, because there are fewer distractions."
"From a biological point of view what the baby is doing is completely normal and sensible. It just doesn't fit in with our 21st-century expectations."
So there you have it, perhaps the dark circles and exhausted Google searches of 'can you die of tiredness?' are worth something. Ha!
