For context, Jamie-Lynn has two sons, 11-year-old Beau and 6-year-old Jack, with her husband, Cutter Dykstra, while Christina shares a 14-year-old daughter named Sadie with her husband, Martyn LeNoble.

Valerie Macon / Getty Images Christina then revealed a comment that Sadie recently made during a fight that had left her devastated. "We got in a big thing the other day. Sorry, Sadie, but it has to be said. She says, 'I miss who you were before you got sick,'" she recalled as Jamie-Lynn and Kelly sighed empathetically. Kevin Winter / Getty Images "That's just like, knife to the heart. 'Cause I miss who I was before I got sick, too. Very much so. Every day of my life, it's such a loss," she said before getting emotional. "See, now I'm gonna cry," she added. Jamie-Lynn then revealed that her two kids respond to her MS in "very different ways." "My older son, he looks at me like, 'You're gonna beat this thing one day, mom,'" she detailed. "He congratulates me all the time for how hard I work, he tells me I'm doing amazing, he's my cheerleader." View this photo on Instagram Instagram: @jamielynnsigler "My little one hates it. He's mad that I can't run like all the other moms, he points out all the time that I walk like an old lady," she said, before noting that she finds this response "healthy" and completely welcomes it. Bravo / Getty Images "I want him to be able to express himself with me; I don't want him to feel bad because of how he feels about this, because it affects our entire family," she explained.
