"The best part about being a mom is coming home and seeing my son recognize that it's me. He gets all excited. It's in his hands, it's in his toes," Tamera says.

Jealousy, what jealousy?

After a shaky start, the relationship between Tia Mowry-Hardrict and Tamera Mowry-Housley‘s sons has taken a turn — for the better!

According to Tia — mama to Cree Taylor, 2 this month — the boys’ bond is stronger than ever.

“Cree absolutely loves [his cousin] Aden. When he first saw Aden today, he gave him a really, really nice hug. It was so adorable,” Tia told PEOPLE during the launch of Milky at A Pea in the Pod in Beverly Hills.

“When Aden cries, he’ll go ahead and put his little pacifier in his mouth. It is the cutest thing. My sister and I are loving it.”

Although both Tia and Tamera are busy juggling full plates, the twin sisters have teamed up to launch Milky, an all-natural drink that nursing mothers can take to boost their milk supply.

“I feel on top of the world. This is like a dream come true. I don’t want to sound corny, but we’re helping moms,” Tamera says. “This is what we’ve always wanted to do. To see the moms’ faces. They’re so excited about coming here and having hope that they’re going to be able to nurse as long as they possibly can. [It] means a lot.”

Despite their success, Tamera admits she never imagined spending her life in the spotlight following their hit show, Sister Sister. “I went to college. I thought I was going to become a kindergarten teacher, and then this happened,” she says of her career. “I never stopped because I love what I do — and people still love us, thank God.”

But balancing both their professional and personal lives comes with its fair share of challenges. “I’ve been very, very busy being a mom, being a wife, being a sister and helping launch Milky. I really take everything a day at a time. I kind of focus on one thing at a time. I can’t try to do everything at once,” Tia says, before correcting herself.

“I take it an hour at a time, actually. Not a day at a time,” she adds.

As for Tamera, the first-time mama is still adjusting to her new sleep schedule, learning to navigate her day on a limited amount of shuteye. “I knew I was going to be sleep deprived, but I didn’t know it was going to hurt. When you’re sleep deprived and it hurts, that’s on a whole different level,” she says.

“Imagine you have to take care of another human being and then on top of that, lose your baby weight all at the same time. You just do it. You turn into mama mode. It’s survival mode.”

Fortunately, her greatest job comes with plenty of incentive — and a big pay off! “The best part about being a mom is coming home and seeing my son recognize that it’s me. He gets all excited. It’s in his hands, it’s in his toes,” Tamera says.
