Adam Peaty's mum, speaking to Radio 5 live, says the 50m and 100m breaststroke gold medallist used to be "petrified of water".
Caroline Peaty said the 20-year-old from Uttoxeter would scream during bath-time when he was a child.
"He wouldn't go in the bath and he wouldn't stand under the shower - he was completely petrified of water," said Caroline.
"Like I've done with all my children, I wanted them to swim to keep safe. My friend took him the first time because it was breaking my heart.
"It took about a week then we got him used to water, then we got him into swimming lessons," she added.You can hear what she had to say here.
