Hi there, just curious... I'm an introvert, so is DH and DS, so much as we enjoy being around other people, we do find it tiring. I remember as a baby, DS would crash out and take an unusually good nap, provided we caught him before he was OT and he was in his own cot, if we'd been around lots of other people for a while. Not so if OT/OS - then he'd just get crazy hyper and eventually have a meltdown! DD on the other hand, has always appeared to me to be more extroverted and I understand (but can't imagine it!) that extroverts actually get energised from being around other people, right? So today after church in the morning, where crèche was busier than she was used to, she really struggled to nap at her usual time, but seemed more UT than OT. Same again at BT, after we'd been to a party in the afternoon, she just seemed to have more energy than she would have done usually, and not just in an OT/OS kind of way? So anyway, this isn't really a question about sleep as such, just wondering what others have found with their introverted and extroverted LOs - do your extroverts really get more energy by being around lots of other people and get less tired than they would have done at home? And at what age did you notice these characteristics developing?
