“I bow down to these women who just do it completely on their own, but you know, you say it takes a village, and it does because babies need lots of attention,” McPhee said.

McPhee also noted that she “loves every second” with her son but “there are moments that are hard.”

“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. So I love every moment of it,” she shared.
