Blair recalled the difficult delivery in a since-deleted Instagram post on Arthur’s 8th birthday in 2019.

“It was a painful induced labor. He was weeks late according to doctors. I felt fine,” Blair wrote (viaThe Independent). She added that she “fired” a doctor who wanted to perform a cesarean section and explained the pain from inducing labor was “horrific” and that there was no dilation for 37 hours. She said she eventually got an epidural because she “had to protect him.”

“I’m one of those hovering mothers and I know it’s really important to have an independent child, soI’m trying to back off, but it’s hard,” she told PEOPLE at the time. “I love him so much, and he’s so funny and cute to me.”

In acandid and tearful conversationwithDrew Barrymore, Blair admitted that she never felt hope until Arthur was born.

Blair said that she and Arthur do breathing exercises every night at bedtime as a means of staying grounded and close, noting that she talks about some sensitive topics with her son in case something similar ever happened to him or one of his friends.

“We love our kids the most,” she said, “and we realize we want nothing to get in the way of that.”

In anInstagram postshe dedicated to Arthur on Mother’s Day 2024, Blair posed with her son and her service dog Scout for a photo.

“This is the first Mother’s Day in ages, where my sonlets me capture him for a photo. And my love is boundless. Thank you Arthur. I’m the proudest mom. Happy Mother’s Day mamas,” she wrote in her caption.

Blair took four years off after having Arthur

Blair took four years off from acting after Arthur was born, and she would do it again in a second.

“I will never regret taking four years off of work to see and hold him as much as possible, to watch him grow,” she wrote on Instagram in 2016. “I may have to start over career-wise and struggle a bit, but I have this. And I am so lucky. Just the luckiest. Forever grateful.”

“It was to have him be a part of it, help him be in control of maybe like a first image of Mom looking different,” Blair said. “That was pretty easy and a nice moment, and it makes me feel better knowing Arthur has a say — not a say, really, but is included.”

Explaining that Arthur has “had to endure a lot” of her MS battle with her and has remained a beacon of strength for her throughout, Blair told PEOPLE, “He says, ‘Mommy’s not sick. Mommy’s brave.’ "

Arthur has also continued to be his mom’s cheerleader through her MS journey. In an interview forTravel + Leisure’s March 2025 cover story, Blair said her sonpushed her to go outand explore during their recent trip to Paris.

“Normally I would’ve gone to bed, but having a child who likes to walk, shop and see the cool things gets me to go out,” she said.

Upon her own exit from the show, Blair recorded a sweet message to Arthur.

Blair told PEOPLE in 2019 that one of her and Arthur’s favorite activities isplaying dodgeball, albeit a one-sided version of the game due to her MS impacting her reflexes.

“We play dodgeball, but I don’t dodge because that could be so dangerous. Maybe in the future for sure, but I don’t move side to side perfectly, and so I get to just hit him and then he throws it back to me, really chivalrously,” she said. “And then I get to hit him again, and he thinks it’s amazing.”
