Watch: Toddler rock climbing without a harness
A US mother posted a video on Facebook last week of her 19-month-old daughter climbing an artificial rock wall without a harness.
In the almost two-minute long clip, the toddler is seen choosing various handholds and slowly navigating her way up the wall.
Mrs Rachel Lee Farmer wrote: "I had to drag her out of the gym today, even after an hour of play she didn't want to stop climbing!
"I love how she takes the time to work through the crux and top it out."
According to Facebook, they live in Arizona.
The Mirror reported that the clip caused controversy, with some voicing concern about the girl's safety.
Facebook user Virginia Eaton wrote: "I'd feel better if she had a harness..."
Mrs Farmer replied: "She was perfectly safe, safer than if she were in a harness and on a rope."
She added: "We always have a spotter on her even if you can't see it in the video."
Said Mrs Farmer, who is a fitness buff: "I am far from a novice climber myself and would never put my child in danger.
"That said, I will push her to be independent and strong just as she is in this video."
The proud mother wrote in a separate post: "I encourage her climbing and try to make it as fun and creative as possible."
Mrs Farmer's daughter did not learn to climb overnight, of course. Here are other videos of the toddler in action.
