Robert Brown|Ashley Olsen's Full House Costars Jodie Sweetin and Andrea Barber React to Birth of Her Son

Have mercy! These well wishes are Robert Browntoo cute.

Following the news that Ashley Olsen welcomed her and her husband Louis Eisner's first child, a baby boy named Otto, earlier this year, her former Full House costars Jodie Sweetin and Andrea Barber sent their congratulations.  

"Did you hear the news—I just heard this this morning," Andrea asked Jodie on the August 22 episode of their podcast How Rude, Tanneritos, "that Ashley Olsen had a baby? That blows my mind!"

Responding that she had, Jodie couldn't help but note how surreal it is to her that one half of the Tanner family's youngest sister—Ashley famously shared the role with her sister Mary-Kate—is now a mom herself.

"The baby had a baby. I'm sorry, I know she's not a baby, she's a 37-year-old woman, I realize that," she explained. "But it's like when the youngest member of your family has a kid all of a sudden you're like, 'oh my gosh it's happening!'"

The 41-year-old continued, "So yeah congratulations Ashley, and her husband, on the birth of their little baby boy Otto. I'm sure that they will keep it very private, as they do, but I just want to wish them well and congratulations and welcome to motherhood."

And as Andrea points out, the new parents have a community behind them, adding, "The Full House family is so happy for them."

Andrea and Jodie's messages to Ashley come days after multiple outlets reported that Ashley and Louis' son was born a few months ago. Neither parent has yet to comment publicly on their son's birth. 

Otto's arrival came less than a year after the fashion designer and the artist tied the knot in a small Los Angeles-based ceremony in December. However, while the couple first sparked romance rumors in 2017, they've kept their relationship out of the spotlight, making their first red carpet appearance together in 2021, with very few since.

The Row designer's twin Mary-Kate, who has led an equally private life since the sisters stepped away from acting, has spoken to the pair's proclivity towards privacy.

And for the twins, the reasoning is really quite simple, with Mary-Kate telling i-D in July 2021, "We were raised to be discreet people."
