A grandfather in his 70s in Kent, England, picked up the wrong child from school recently and took her to the doctor, leaving outraged parents wondering how such an oversight could have happened.

The Guardian reports that the 6-year-old girl was set to be picked up from Napier Primary School for a doctor’s appointment by her grandfather when the school apparently handed over a completely different child to the stranger. Kent Online reports that the girl that was brought to the elderly gentleman had the same first name and was in the same grade as the man’s actual granddaughter.

The grandfather took the little girl to the doctor on the bus, where the child was presumably examined and was actually prescribed liquid paracetamol (a pain reliever and fever reducer), then the grandfather dropped the girl back at school, where she returned to class. It wasn’t until later that evening when the girl showed her parents the medicine she was prescribed, and her father verified with the clinic, that they even knew what happened.

The girl’s father was outraged when he found out about the incident, he told the Guardian, “"I went ballistic. I was boiling inside. The first thing I thought was the worst. I had to ask my daughter the sort of questions no parent ever wants to ask: 'Did he do this, did he do that?' When your daughter has been walked round town and taken on a bus by a strange man, it makes you sick to the stomach. It's every parent's worst nightmare. Everyone knows to tell their children not to go with strangers, but I want to tell every parent in that school – tell them again tonight.”

The girl’s mother told Kent Online, "Thank God it was an innocent thing done by a confused old gentleman," adding that her daughter is quite shy, and was no doubt confused by the situation.

The head teacher at Napier Primary School said that they investigating the incident, as well as reviewing all safety procedures to ensure nothing like this ever happens again.

With many elderly grandparents now on childcare duty, we’re frankly surprised that this doesn't happen more often, but the fact that nobody at the school even noticed is pretty unforgivable.

Do you ever ask your child's grandparents to take your kids somewhere? Are you ever worried they'll become confused? Tell us below!
