We would do anything for our kids right?
One dad went as far as spending 30 hours and over 6-8 weeks, getting a HUGE chest tattoo to match his son's birthmark.
Derek Prue Sr., noticed his son wouldn't go swimming without his shirt on and realized he wanted to do something to help his son.
"I knew he was self-conscious about it. I saw how he was reacting, and it made me want to do it so that he wouldn't be the only on," said Prue.
Although it was painful and took WAY longer than Prue expected he said it was all worth it.
"Now we have the same marks for life.”
