The Sopranos alum stopped by the Today show Thursday and shared her experiences of living with multiple sclerosis while being a mom to 3-year-old son Beau Kyle. “I tread lightly with telling him about my condition because there’s not a lot of it that he can grasp,” the actress, 35, said of how her MS diagnosis affects how she interacts with Beau. “I would never use the word ‘sick’ because I don’t want to overload or scare him,” she explains.

The actress and jewelry designer shares parenting duties with husband Cutter Dykstra, a pro baseball player, whom she married in Palm Springs, California, early this year. And even though their son is still very young, he does understand the basic concepts of his mom’s limits. “I tell him that Mommy’s legs can’t do that and if he wants to play with me, we have to play a game where we’re sitting down,” she explains of how she helps her son pick and choose what activities they take part in together. “He gets it for the most part.” Sigler, who was diagnosed with MS when she was 20 years old, notes that there are plenty of ways the twosome find time to bond, from her taking on positions like pitcher or goalie in sports, creating art or watching a movie together. “He’s a mama’s boy, so he’ll embrace any time spent together,” Sigler admits. “But he’s 3 years old, so he has his tantrums, but we manage as a family and do the best we can.” It’s all worth it for Sigler, considering what her little man gives back to her. “Beau gives me a reason to look forward to every single day,” she says. “He’s the light of my life.”
