The happiness, the joy, the masses of shiny plastic: all part of the perfect Christmas day.
Sadly, many a magical moment has been ruined by the insatiable excitement of the up-all-night little ones itching to see Santa. Don't they know you've got presents to unwrap?
Inundate those interrupting youngsters with gifts from this list and they'll be occupied for weeks - leaving you lots of time to enjoy your own wrapped-up wonders (which you definitely didn't buy yourself).
SAM Labs Curious Cars (£149)
SAM Labs' Curious Cars is a fun kit that allows kids to bring their toys and inventions to life, through the magic of coding.
Inventive little tykes can knock together their very own remote control cars using nothing more than a bunch of modular SAM blocks, the app, the models and their own imaginations, all while learning the basics of coding in a new and accessible way.
Fast forward a few years and they'll be hacking into your Jag while rewiring the horn to play la cucaracha. Bless them.
Smart R2-D2 (£100)
BB-8? That’s so 2015. Christmas 2016 is all about Rogue One’s top toy tie-in: the Smart R2-D2.
A fully interactive robot that'll respond to your voice and actions, this roving dome-top will move and bleep happily around the house, leaving adults of a certain age on the brink of happy, happy tears.
There's an app, too, which works as a remote control. You can even program your - sorry, your kids' - new droid for 'missions'. There's no C-3PO included - but you can always dress up.
LeapFrog LeapPad Platinum (£65)
Spend £65. Teach your kids. Get your iPad back. Everyone's a winner!
LeapFrog's LeapPad Platinum is a fully functioning 7in tablet, equipped with a software platform designed to be both intuitive and safe for little ones. There's an app store and internet browser, but parents can control access to both - as well as setting time limits on usage.
The bumper-wrapped tab can also be installed with a wealth of educational games available from the Leap Store - more than 1,000 - all cleverly disguised as frivolous fun-fests (though they don't all come cheap).
Discovery Channel 360 Super HD Microscope (£48)
If you want kids to pay attention to anything these days you’re best off putting it on a mobile phone screen - so trick them into learning about science and nature by buying them this microscope and attaching your phone to its eyepiece.
The Discovery Channel 360 Super HD can magnify by 60, 120 or 200x, using your phone to display and take photos of what’s underneath. Now you just need to tear them away from the phone long enough to find something to look at under it.
Is three too young to start coding? Not according to the brains behind Cubetto. This friendly wooden truck is in fact a well-disguised coding toy, operated by slotting colourful plastic pieces into a simple board.
Certain pieces make the truck move around, whilst a function piece allows your little genii to create loops. Before you know it, they'll have crafted a connected train set triggered by nothing more than a Lego brick.
Marvin's iMagic (from £19)
Marvin's Magic boxes have long fascinated wannabe David Blaines, but they're not all that gadgety. Until now. Meet Marvin's iMagic: teaming traditional props with augmented reality via an iOS and Android app, it's a truly 21st century take on sleight of hand.
Gasp as objects jump from your phone screen to your hand! Gawp as mysterious lights dance before your eyes! Gibber as you accidentally summon Beelzebub into your Samsung Galaxy S7! OK, maybe not that last one.
A deluxe version includes several more props for an extra tenner.
