Since having a kid:
We do a small number of presents Christmas Eve early evening which normally involve a classic kids game (think buckaroo or kerplunk), New pyjamas and a movie. We play a couple of rounds of the new game and watch the movie whilst sitting in our new pj’s before the kid goes to bed at 7:30:8:00.
Christmas Eve after the kid has gone to bed normally involves a few brandies, a coupe of vodkas and the classic Christmas movie Die Hard, plus a random movie pick (this year my wife picked Man on Fire, I was gunning for commando but got outvoted......somehow??!!???!!)
Christmas Day morning we wake up anywhere between 8:00 and 10:00 and the kid opens his ‘santa’ stocking in his room. We normally sit on the bedroom floor and see what Santa has brought him.
Breakfast and then main presents, before heading over to my folks for dinner.
