Actually this sounds like parenthood ;P

Seriously do you see an improvement in the ability with age? There's a
mechanism in children/adolescents that prevents them waking in this way
(so
siblings won't disturb them), but I'm yet to find any clear work on
whether
there is a hard turn off age on this. Could be an issue in young
soldiers
(probably younger than recruiting age for western armies) I guess.
