Do you ever look at your kids and wonder, where do they get all this energy from?!
They can be bouncing off the walls within a few seconds of waking up and they don't seem to stop until it's time for bed again.
They want to climb on EVERYTHING, touch EVERYTHING and unpack EVERY draw and cupboard in sight.
Sometimes it can be hard to explain what it's really like, but dad Ian Muir's clever photography and editing skills highlight it just perfectly.
He took lots of photos of Millie, two, getting up to all sorts of mischief and edited them all together.
He said: "Millie is a little bundle of energy as most two year olds are.
"She could talk the hind legs off a donkey but walking didn't come so easy to her.
"She's only just mastered that in the last month so shots like this wouldn't have been possible just a short while ago.
"Now she's up on her feet we can get up to all sorts.
"Millie spends her mornings with me before I head to work in the afternoon, this means we can get up to this kind of mischief."
Ian says it took a few days to achieve the perfect shot and Millie was the perfect model - but she did need bribing on the final day as she was getting a bit bored of it.
Ian, who lives in Dunfermline, Fife, said: "This one was our third day in a row of trying and Millie had definitely had enough of my nonsense so I’m glad we got a good one."
His partner Sally Williamson shared the photo online with the caption: "Five minutes in the life of our two-year-old."
Other parents are loving the brilliant photo, saying it captures a toddler's energy perfectly.
Ian has explained exactly how he made the picture so other parents can give it a try themselves.
The most important thing is a tripod which doesn't move, as this will allow you to get the frame exactly the same.
You then need to take lots of different shots being careful not to overlap your positions.
Ian said: "Use the 10 second timer or a wireless remote for the dangerous shots like on the car, I'm standing to the side ready to catch her if need be and I edit myself out.
"Do the difficult shots first, if the little one loses patience at least you’ve got the difficult ones.
"One of the hardest things is making sure the light remains consistent throughout the shots. If you have one darker or lighter then it's hard to blend the shot in.
"I put a flash on a stand and pointed at the ceiling, the flash is just inside the living room to the left.
"The problem I had here is that the light was changing outside as it was a cloudy day, this made it brighter/darker inside. If you look close enough you’ll see some mistakes but I just get away with it I think."
Ian then used the computer programmes Lightroom and Photoshop to edit all the pictures together.
It sounds complicated, but luckily he's told us EXACTLY what to do.
He said: "In Lightroom I select all the shots, right click and then choose 'Open as layers in Photoshop'.
"Once they've all loaded I select them all and then auto align them (edit>auto align).
"Then I use layers and masks to bring her through on each shot. Once I have all the shots out together I sent the image back to Lightroom to tweak the exposure, change white balance etc."
The image has since been shared thousands of times. We found out about it here.
