A dad says he might tattoo his identical twins so he can tell them apart

A dad who can't tell his identical one-year-old sons apart has made a desperate plea online to parents of other sets of twins to help him out with ways by which he can easily identify them.
The anonymous man wrote the cry for help on  Reddit , after admitting that he and his wife had 'tried everything' to tell them apart.

His desperation is due to the fact that one of the twins has serious health issues and needs medication every four hours.
He wrote:
"If he doesn't have his medication it leads to significant consequences. The boys are completely identical. Even me and my wife can't tell them apart and have been drawing on Adam's arm every day with permanent marker."

He added:

"The twins were at Grandma's and after a bath rubbed off the text, Grandma accidentally gave Aaron's medication to Adam.

"Adam ended up very sick and Aaron in hospital for a week. This is a serious, extreme situation and I don't want to take this risk again. We have had other mix-ups with the boys but it has never wound up this bad."

He said they've tried everything from nail polish to bracelets to anklets to specific colours of clothes for each boy but they want something more permanent to identify them with.

"I read online about someone tattooing a single dot on one of the twins and also about piercing ears.

"I really hate to say it, but we are here. I need to do something permanent. I could have lost both my sons last weekend and I'm desperate.

"I am really only after permanent solutions. Believe me when I say we have tried everything else before and it didn't work. Please help me. I don't want to lose my boy." 

Some reddit users gave some suggestions. One said:

"My friend has a similar issue and used to paint her boys' toenails. She ended up getting a dot tattooed on the bottom of one boy's foot".

"I think the ear piercing is a great idea, very low risk. Babies often have their ears pierced while they are young with no extreme side effects"
