The mother goes on to explain how her previous trips to the store during Christmas time used to be very painful because of her children's behaviour.
"Toys are out in full force ... and of course my kids WANT IT ALL," she wrote.
"Obviously, I would love to have sweet, well-mannered, non-greedy, chill kids, that don't ask for all the things ... but I don't. So drop your judgement Karen, and stop reading if you have kids like that.
"Now ... if you have kids like mine ... that want the shiny amazing things that fill Target, the grocery store, Office Depot, the gas station, and pretty much everywhere you go this time of year, this is for you."
Watts said that it's as simple as taking a picture.
"Pause for a second, comment on the thing they're pointing out, and say, Let's take a picture with it and send it to Santa so he knows you want it!'
"Note: you can send it to Santa, grandma, TeeTee Stephanie or whoever it is you can pawn it off on. Totally up to you and can be different every time.
"Magically, Emmie smiles, says cheese, asks to see the picture, then PUTS THE TOY DOWN AND WALKS AWAY.
"It's magical. No tears. No tantrums (by either of us). And she forgets about all of them within minutes."
After sharing the tip she added "You're welcome" at the end.
