Michael Phelps' wife, Nicole Phelps, made her feelings known about her sons living up to the swimmer's name
Michael Phelps' wife, Nicole Phelps, recently appeared on the 'Between Us Moms' podcast, where she opened up about raising her kids. She made her feelings known about how she handles the pressure of her children living up to their father's name.
Talking about her eldest son's goal and opening up about making him understand the pressure, she said,
"Boomer wishes to be a professional soccer player, and I hope that if that's what he wants to continue to do, that's where he lands. With that, both Michael and I recognize the amount of pressure that will come with it, and we hope to kind of wade those waters with him today and teach him, versus waiting until he's 16 years old, and it's like, my dad's Michael Phelps, why am I not the best? So it's, how can we make you, not make you, how can we help you become the best over these next few years versus you will be the best," said Nicole Phelps (31:05 onwards).
