According to a source, Katherine is officially in "new mommy bliss mode" after giving birth to Lyla in August. This is Katherine's first child and the second for Chris, who shares son Jack, 8, with ex-wife Anna Faris.
"She took the first month off from most of her work and loved being able to do that. She just reached the six week mark and is looking forward to getting out and doing more," the source shared with E!. "She has been very cautious with COVID and the air quality in LA so has been staying in."
Though Katherine and Chris have had some "help getting situated and helping the baby with sleep," both parents are "very hands on," said the source.
"They are both home and with the baby at almost all times," added the insider. "They have had some family visit for short periods of time but mostly have just been getting adjusted to their new little baby."
The Gift of Forgiveness writer previously told E! News how her mother Maria Shriver, a journalist, author and the former First Lady of California, inspired her to become a parent.
"I want to be a sponge always around my mom and just observe as much as I can from her because she has been the greatest mom and continues to be the greatest mom to all four of us," Katherine shared. "We're really lucky, so if I can be just a little bit of the mom that she is then I'll be lucky."
In fact, Lyla was given the middle name Maria after Katherine's mom — which makes sense, considering a source claims Maria also helped set the parents up!
Shortly after Lyla's birth, Katherine and Chris took to Instagram to share the good news with their followers, along with a sweet photo of tiny Lyla's hand.
"We are beyond thrilled to announce the birth of our daughter, Lyla Maria Schwarzenegger Pratt," Chris wrote. "We couldn't be happier. Both mom and baby are doing great. We are extremely blessed."
