We’ve teamed up with The Photographers’ Gallery, Thames & Hudson and Guardian Family for Family Photography Now, a brilliant 40-week project inviting people to submit photographs linked to the theme of ‘family’. For our part in the project, which starts today and runs until the 23rd September, we’re asking you to send us a photograph that captures a moment when your kids have been left to their own devices and their active imaginations have taken over.

Our submission (above) captures the moment when, on holiday, our editor-in-chief Charlotte Philby discovered that her family’s mobile home had been transformed into base-camp in a game of Spy-Quest which started with her thee kids and ended up involving 97% of the campsite’s Under-11s – all of whose mission it was to spy on, and finally capture King and Queen Macaroni (i.e: Charlotte and her husband), using a selection of deadly weapons including a sword made of privet twigs and a canon made of ice cream – which as you can see in the picture her middle child has just eaten. 

To get involved all you have to do is head on over to Instagram and post a snap of your kids having been left to their own devices to play, and then tag:

@motherlandnet
@thephotographersgallery
@familyphotographynow

And use the hashtags #familyphotographynow and #FPNimagination

The best snap will be published in Guardian Family, and we’ll also showcase a selection of our favourites here on Motherland. 

Happy snapping!
