A 'birthing selfie stick' is on sale for expectant mums this Christmas - but there's a catch.
The product promises to enable mums-to-be to capture every contraction and share the experience with the world.
It's reportedly being sold on Amazon as the perfect present for friends and family due to give birth, at a price of £6.
The product description reads: "A baby’s arrival is a magical event. And there’s only one chance to get the shot.
"Birthie Stick is sturdy and fully adjustable, allowing you to capture every contraction with confidence."
The creator Brandi Rae added: "Why selfishly live in a moment when you can be sharing it with the world?"
But the product is actually a big prank - and is in fact just a box in which you can place your real present inside, the Sun reports.
On the packaging, which is part of the trick, it says: "Childbirth isn't something you want to keep to yourself.
"The Birthie stick was designed to provide steady, high quality video of the blessed event using just a smartphone.
"So, friends, family and followers can enjoy a close up perspective of your baby's emergence from the womb."
It adds: "Content doesn't get any fresher!"
The product description advises you to keep a straight face as you watch your friend open the box and realise it's all a joke.
