In an August 2023 episode of "Outdaughtered," the Busby quintuplets talked about their latest goal: bike riding. As her other sisters, Parker, Riley, and Olivia Busby, boasted about their bicycling skills, Hazel Busby quietly sat with a noticeably nervous expression. "I'm not excited to learn how to ride my bike," she admitted (via People). 

This hesitation to learn new skills was a cause of concern for parents Adam and Danielle Busby, with mom and dad offering a different approach to dealing with their daughter's struggles. Adam was worried that Hazel's trepidation to learn how to ride a bike had to do with how her vision shifted when she moved more quickly. However, Danielle wasn't as ready to place blame on Hazel's congenital nystagmus.

"Look at Ava," Danielle argued. "Ava gets nervous to go fast on a bike and is kind of still scared of it. I don't know if it's vision or not. I don't wanna jump to that being the thing every time. Because we wouldn't second guess that if it was any of the other girls. But because Hazel has nystagmus, we must immediately say, 'That's what it is.'"
