“She was checking me and felt my water bag bulging, but still not popping, which was wild. And so, I was like, ‘Well, should we break it?'”

“‘She goes, ‘Well, you can.’ I’m like, ‘What?’ I was like, ‘Are you serious?'”

And then, she broke her own water. “I reached my finger up there, and I’m feeling and it was crazy. I could totally feel this little bag — it feels like a water balloon, but with a bit tougher skin.”

Rumer was instructed to push on the bag during her next contraction.

“It was like I pushed a little bit. Like, I pushed — well, I didn’t push a little bit, I pushed harder than I’ve ever probably, but it was literally like I pushed, her head was out. I pushed again and her whole body was out,” she recalled. “There was no pause. There was no pause in between. It wasn’t one of those moments where it was, ‘Oh, your head is out.'”

“But then, as soon as they untangled her, she was in my arms,” the new mom said, calling the experience " the most ecstatic, joyful moment of my entire life."

“I just started sobbing with joy. I have some of the most beautiful photographs of it of just me looking at her, and looking at my sisters, andlooking at my momandmy mom holding me,” she shared.

“My sister actually told me something later that I didn’t even realize I said. I looked at Louetta at one point, and I said, ‘I missed you so much.’ I thought that was so sweet because it truly was like this moment of, ‘Oh, yes! We’re back together.'”

“It’s like, ‘Oh, yes. This person who I’ve known and I’ve been waiting for forever, here you are.'”
