> Research has shown that sleep is important for both mind and body. Sleep is vital for learning and memory and long-term sleep deprivation can lead to depression, compromised immune function and other chronic health problems. As the father of three under 5, I can testify this is absolutely correct(!)

Either you've multiple wives, or you broke the three year rule, none of which is good. Or maybe you had twins or triplets, that's also possible.

  What's this 3 year rule that I have also missed then?
  - rat9988 8y ago
    A rule that doesn't exist.

      If this is what is meant by 3 year rule, then in my opinion, this is utter nonsense. Having the 3 youngins play and bond together at a similar age is why we deliberately had them as close as possible. Its great to see the bonds develop.

        It’s not nonsense. It’s optimizing on a different metric than the metric you chose. Do you have some evidence that being one or two years apart bonds siblings better than being three+ years apart? My sister and I are three years apart and we definitely always had a strong bond. I can’t imagine a year or two would have made a difference. Our other siblings are as far as decades apart from us and we are less close (still close though), but we also didn’t grow up together - my sister and I had already flown the coop. I’d guess there are some limits in between there, but it’s just a guess.

        Off course, it is not the case that a 3yr+ gap means no bonding, but I think each year gap makes a massive difference when they are young.

  I was born two years after my older sibling, and one year before my younger one. What is this three year rule you're talking about?

It's most apparent in young children. Children generally behave fine when they get good sleep and become monsters when they have just a few less hours. Often being overtired becomes a feedback loop where they refuse to sleep and then become even more exhausted.

  > Often being overtired becomes a feedback loop where they refuse to sleep Often it's true for adults too. When you're overtired, it's sometimes harder to sleep. But why should that be? It doesn't make sense. Any ideas?

    There should be no reason to be overtired so your body reacts by keeping you awake to deal with it until the stressful events are over but this is stressful by itself. And modern city life has no shortage of stress.

    My guess is cortisol and possibly anxiety surrounding sleep.
  - muzani 8y ago
    Part of it is when adults get worried about the lack of sleep, and they get stressed out, which keeps them awake. Cortisol is really good at it.

  I'm always getting angry that most countries force many kids to be sleep deprived for ~12 years. I was one of them. I just can't operate properly before 10a.m. and even if I'm super tired it's very difficult to fall asleep before 1a.m. Furthermore my body wants 8-9 hours of sleep. Research has shown it's not entirely possible to shift our inner rythm, so I really hope (more) schools start offering different timeslots for classes to start. I'm also confident there are enough teachers who willingly start two or four hours later and with flex time enough parents who happily bring their kids 2 or 4 hours later.
