A mom has left the internet divided after tattooing one of her twin boys so she can tell him apart from his brother.

It's a controversial one...

Now, there's nothing quite as rewarding as being a parent.

The love between you and your child is something unlike any other feeling on earth… It’s a pretty magical thing.

But that's not to say it's easy...

Being a parent is basically the hardest job on earth – and the pressure to be a perfect parent can make life even more stressful.

Parenthood can be incredibly tough...

Newborn babies are hard work, that’s for sure.

Not to mention if you have twins.

That's 2 lots of screaming babies, 2 lots of diaper changes, and 2 lots of babies wanting milk.

And twins can offer a further issue to some parents.

How do you tell the 2 apart?

Well, on mom came up with an innovative solution...

But it's safe to say it's been rather divisive - both online and in her real life.

In order to help the daycare tell her boys apart...

A mom shared on Reddit that she'd given one of her boys a tattoo... But for a reason you might not expect.

On paper, it sounds pretty crazy...

But once you have the full story, it really isn't as bad as it sounds.

Here's the story.

"I have 2 beautiful fraternal twin boys. Jack and Adam. Thing is Jake has a condition. Without going into detail, requires a shot once a week. I went back to work and MIL offered to watch the babes. Worked very well until a month ago when she gave the shot to the wrong kid," the mom shared on Reddit.

"Now they may be fraternal but they look identical. I'll be honest my husband and I even mix them up sometimes. Everyone does."

"She immediately noticed her mistake called 911 and they were transferred to hospital. He was never in danger. Its a very slow acting medication that, at worst, would have given him diarrhea in a few days."

"This daycare has a nurse cause some of the kids have medications so she new what to do but the worry of mixing up the kids was a valid concern."

"Doctor recommended a medical tattoo. Explained they tattoo a freckle, no bigger then the end of a pencil eraser, on an area of skin that's easily seen while the child is under mild sedation similar to dental offices. Because of the area it usually fades in 2-3yrs."

"So after discussion with my husband we did it."

"He has a 2mm brown freckle on his earlobe. From entering the office to leaving it took 30 minutes. Never felt a thing."

"MIL lost her shit the second I mentioned a medical tattoo."

"I tried to explain but she just freaked out so I put both kids on the floor and told her to pick up Jack and find the tattoo. She picked up Adam So I handed her Jack and after 20 minutes still couldn't find it. Stripped him to his skivvies. I finally pointed it out and she went 'That's just a freckle' I just said... 'My point exactly. Adam doesn't have a freckle there.. So that's how daycare can tell them apart.'"

"Once I explain to others and they fail to find it they understand but they still think I went to far in tattooing my child and altering their body."

"She's still p****d and ranting." What do you make of this story?
