I'm not convinced its a military trick rather something forced by necessity. I used to be a terrible sleeper, it usually took an hour to fall asleep and would regularly wake for multiple 30-40 min periods during the night and wake up exhausted. We're now on baby no.2 and I can fall asleep in a few minutes any time from 6pm on. Just close my eyes and expect sleep and it comes. 10 minute power naps are great. The ability to fall asleep quickly was forced on me by baby no.1, being woken up multiple times per night and having to fall asleep quickly was a matter of what felt like survival. I'm sure military training causes the same exhaustion and the body learns that it needs to be able to sleep when it can. I'm also sure that sleeping to 12 or 1 on the weekends to recover is detrimental, getting to sleep on a Sunday night was the worst as would not be tired but it would start the week on a the wrong foot. Any other parents in here have the same experience?
