Katharine McPhee Admits It 'Takes A Village' To Care For 7-Month-Old Son Rennie: 'I Bow Down To Women Who Do It On Their Own'

Singer-actress Katharine McPhee became a mom for the first time this February when she and husband David Foster welcomed son Rennie. And though she "loves every second" of parenthood, she's not afraid to disclose that "there are moments that are hard."

"I bow down to these women who just do it completely on their own," she shared with PEOPLE. "You know, you say it takes a village, and it does because babies need lots of attention."

In fact, the Smash star insisted there's nothing to be ashamed of when it comes to needing an extra set of hands.

"I think it's healthy for babies to have multiple people around them who love them, friends, families, nannies," she noted. "I mean, whoever you can, just [to] help you out — and it also, in turn, helps the baby."

McPhee knows that motherhood comes with ups and downs, so she just tries to focus on the positive when things get tough.

"Honestly, I love every second with him. I really do. I'm not one of those women that's just going to say like how hard it is, because there are moments that are hard and you're tired but I just keep reminding myself that it's just a moment in time [and] that I'm never going to get this time back," she explained. "So I love every moment of it."

And while Rennie is still too young to cause any real mischief, she "can't ever imagine" herself getting mad at him since he's "so sweet right now," she said.

The tot, who's Foster's sixth child, is named after one of the musician's relatives — though the couple didn't choose the moniker until the American Idol alum was in labor!

"We had a couple names, but my husband was on a text chain with his sisters and one of his sisters suggested an old family name," she explained. "It was his great-grandfather's name, his great-uncle's name, so it has a long history in his family. My husband said, 'Hi, Ren Foster,' and so we said, 'That's a good name. It's a strong name.'"
