Mitchell has also been using her time to help those in need. On Saturday, she teamed up withFirst Star— which provides foster youth with university-based college-preparatory programs and more — to give the teenagers BÉIS luggages. Each piece was filled with thoughtful items including sneakers and school supplies, and the teens were excited to receive their gifts in time for the holidays.

“I just think that First Star is such an incredible organization,” says thePretty Little Liarsalum. “What they do for the kids in the foster-care system is incredible. Offering mentorship programs and the support they need to get them in school and have that education is so crucial.”

“A lot of these kids are going from place to place and they have a garbage bag to put their stuff in and no one should have that,” Mitchell continues. “So I’m happy that wecould offer some stuff to help themwith this new, exciting chapter in their lives as they’re going to school.”

“These kids have had the misfortune to be born into the wrong family, with the wrong parents, and bad things have been done to them at no fault of theirs,” Peter Samuelson, co-founder and president ofFirst Star, tells PEOPLE. “Then they’ve gone into institutional care or living with strangers. Some have been in 15 to 20 places — how do you live a life if that’s the case?”

And Atlas has already been showing bits and pieces of her personality at just 7 weeks old. “She doesn’t really look like her dad or me yet,” Mitchell tells PEOPLE of her little one. “She’s her own person and that’s kind of fun. But her personality, she’s super happy, super talkative.”

Atlas also loves to eat. Mitchellsays breastfeeding has been apleasant experience for the two of them, though that could change. “Maybe when she gets teeth and she starts biting [it might get tough],” the star says. “But up until this point, she doesn’t have teeth and we’re doing well.”

“Everybody has their own kind of journey with motherhood, with breastfeeding … this is what works for us right now and it’s nice,” she adds. “Just waking up, having her next to me when we go to sleep, is such a fun thing.”

Mitchell says her little one really shows herpersonality when it comes to breast milk. “She is a little feisty one because even when there was nothing, she would just be like, ‘Weh,’ and then when she comes for the boob she has this face that’s scary. It was the funniest thing, but it was also terrifying.”

“I’m enjoying this phase right now without the teeth. She gets aggressive and she’ll hit my boob like, ‘Mama, get it out,’ and she’ll look up and I’m like, ‘Whoa, okay, it’s coming, relax,’ ” the actress jokes. “If I don’t go fast enough, she pounds it and looks up.”

As for the future, Mitchell ishoping her daughter willcontinue joining her on adventures: “She’s so good and she’s such a good traveler too, so I’m just hoping that continues and she can be my travel buddy.”
