A teacher can often be the third most important adult in a child’s life – behind two parents, that is.

Nancy Bleur is a lovely and caring kindergarten teacher from Iowa. She absolutely adores her students and goes out of her way to make them happy.

One day the 54-year-old teacher noticed that 4-year-old Camden in her class wasn’t his usual self. She made a decision to have a little chat with him to see what was up. That’s when the boy started telling her about his father… and it made her heart sink. She felt like she had to do something – and fast.

As it turns out Camden’s father, 34-year-old Darreld Petersen, was very sick. Nancy realised just how bad, which made her even more worried as she couldn’t bare the thought of how it was affecting little Camden. That’s when she decided to call the dad up.

There was something seriously wrong with Darreld’s kidneys that made them function at just 20 percent of their capacity. During his dialysis treatment, he looked so sick that poor Camden was terrified when he saw his daddy.

Nancy decided to help the family in any way she could. If you think she offered to babysit, help with the groceries, cook or any other daily chore, you are not alone. But Nancy went much further than that in lending her hand.

She offered Darreld one of her kidneys.

Miraculously, she turned out to be a perfect match, meaning it was relatively straight forward for her to make good on her offer. All she had to do was fill in the necessary paperwork.

“I was really excited about it. I was ecstatic. I don’t know what I would’ve done for closure if I wasn’t [a match],” she says.

Camden’s dad was in shock and delighted with Nancy’s extraordinary offer. She would be saving his life.

Darreld told ABC News:

“It’s just amazing. There are people waiting every day for a kidney, for an organ in general. I wish there were more people like her. She’s giving me a second chance at life,”
