To say new momPorsha Williamsis glowing would be an understatement. Even over the phone, the brightness shines through.

“I’m just so happy,” theReal Housewives of Atlantastar, 37, tells PEOPLE of newborn daughterPilar Jhena— her first child, whom she shares with fiancéDennis McKinley. “She’s everything I ever wanted and I still can’t believe she’s here.”

In the trailer alone, there were tensions with McKinley over their living situation and a heated battle between his and Williams’ mothers. The special also documents Pilar’s birth — which looked blissful but was anything but.

Adding to Williams’ struggles was the fact that her body didn’t produce enough milk for her to breastfeed Pilar, which is an experience she calls “the hardest part” of new motherhood.

“It was something I was pretty nonchalant about in the beginning. Like, ‘Okay, if I can breastfeed, that’s fine. If not, I’ll put her on formula.’ It was that simple,” Williams says. “But once she got here and you’re looking at your daughter, you want to give her the world. You want her to have everything that’s the best for her. So it was really difficult for me to come to the realizationthat I couldn’t pump enough milk for her.”

Things got so tough that Williams said she was almost sent “into postpartum depression.”

“I just had to come to terms and be okay with itthat I wasn’t able to breastfeed. I don’t even know if my body was ready,” Williams says. “My fiancé was very supportive, some of my friends were very supportive — they just reminded me that it’s okay. You still are a great mommy and you still love her as much as anybody can love her child. And it’s all right. She’s going to be okay. She’s going to get everything she needs.”

And Pilar certainly does seem to have everything she needs. “She’s a month, healthy, happy and got a great weight on her,” Williams says.

She has a nice head of hair on her head, too. “That’s where that heartburn came from!” Williams says. “I was prepared if she didn’t have any, though. Ihave headbands, beyond. ButI didn’t really need them. I cannot wait to give my little girl one of those Go Naked ponytails. She is our next model, I know it!”

There is one big thing Pilar has in common with her superstar mom.

“She’s a diva,” Williams says. “Literally, on her one-month celebration is when I saw the most of her personality. When she wants her bottle, she wants it right then. And when she’s done, she’s done. She’s on her own time schedule. She runs our house, literally! We are all on PJ’s beckoning call.”
