“We were like, ‘Oh, should we have another kid?’ ” Hilariatold PEOPLE in November 2017, while pregnant with Romeo. “We were like, ‘You know what? Let’s try something different — let’s try.’ [With] the other ones, it’s not like we were like, ‘Oh my God, how did this happen?’ But this is the only one we [planned].”

“She was a little bit disappointed. [She said,] ‘How about you have a girl first, then you can have another boy?’ I was like, ‘It doesn’t work that way! I don’t get to choose,’ ” Hilaria shared. “She’s like, ‘No, you don’t understand, Mommy. It’s going to be a girl.’ I was like, ‘No, I promise. I promise you it’s a boy.’ ”

Despite already having an older sister in Ireland, Hilaria told PEOPLE of Carmen, “She is committed to a fifth child.”

Hilaria echoed Carmen’s thoughts again on theTodayshow in July 2018, saying, “She does have a sister — she has Ireland, and Ireland is so wonderful and they have a great relationship, butthere’s something about a little sisterthat she really wants.”

When hostHoda Kotbasked if her husband was on board with more kids, the yoga instructor revealed, “Alecthinks it’s very possible. He comes from a big family.”

“People are like, ‘Oh, they must be Catholic’ or ‘Oh, she must just want all of his money.’ I’m like, ‘If I wanted all of his money, why am I having so many children? Children are expensive!’ ” she joked to PEOPLE in her November 2017 interview. “Seeinghow much my daughter wouldlike to have a sister, do we try for that? I have no idea.”

But theMatch Gamehost had his reservations. In March, hetold PEOPLE of his hesitationabout expanding his family further, “When my kids graduate school, I’ll be 85.”

More recently in June, Hilaria revealed exclusively to PEOPLE that the twoaren’t done giving their children siblings.

“They’re my favorite things in the world so why not?” said theMom Brainpodcast co-host of her kids.
