Chris Pratt on Sweet Morning Routine and Milestones with Daughter Lyla: 'She's Such a Wiggle Worm' Last month, Pratt opened up to PEOPLE about the "special time" he shares with Lyla in the mornings, during which the actor recently discovered a secret soothing technique. "She's such a little wiggle worm," Pratt said. "The 20 minutes before I go to work is like our special time. And we sit out on this little chair or this little couch thing on the balcony, in front of the fireplace and there's this little heater, and we have our time together. It's like kid time. She's always wiggling around and you have to distract her with the toy. She doesn't want to just cuddle yet." Pratt said Lyla has started teething and has been extra wiggly, but on a recent morning during their "special time," he learned a new way to help relax her.

"I just started brushing her hair with it. And I realized like, 'Oh, she's going to love to go to the spa when she grows.' I could see her just relax into my lap. It's kind of the first time in her life that I've ever been able to just have her really relaxing on my lap." "I combed her hair for like 15 straight minutes. The only other time she's really ever done that is when she's peeing on me. So she'll like zone out and I'm like, 'There you go there, there you go calming down. Okay, you're peeing, that's why you stopped wiggling.' And so we had a really nice moment this morning," he added. Pratt and Schwarzenegger, 31, welcomed their daughter back in August 2020. The couple shared the news and a first photo of their newborn baby girl's hand alongside a sweet announcement about her birth shortly after she arrived. "We are beyond thrilled to announce the birth of our daughter Lyla Maria Schwarzenegger Pratt," the caption on both parents' Instagram posts read at the time. "We couldn't be happier and we feel extremely blessed! Love, Katherine and Chris."
