It's one of the better things about having older kids obs! It's nothing new either - when my parents got our first video recorder it was delivered in the daytime & my DF arrived home from work, read the first page of the instuctions & announced:
'Right, first we have to tune this thing in'
'yep, already done, Dad'
'ok, so lets look at how to record'
'already done, Dad' 
Isn't technology wonderful? It's brought us the ability to hoard loads of beautiful pics
