"I've been up since 3 a.m., but this is what I've wanted my whole life," Nikki said at the time. "The fact that he's here — I'm just so in love and happy." "That's what happens when you're on an infant schedule," added Brie. "But like Nikki said, the love is just so overpowering that even though you're so tired, that bliss just takes over." After giving birth, the sisters were placed into hospital rooms right next to each other, and they got to meet their new nephews for the first time. "What's crazy about Buddy and Matteo is they both have the same scream-cry," Nikki recalled. "It's the cutest high-pitch noise and they're identical. Even their coos are identical and they're so cute. Now, Matteo, he will grunt and like punch my boobs when he's breastfeeding. Artem and I will sit and laugh because it's perfect little punches he'll do. He grunts at me, so I feel like I have a little boxer on my hands." "Buddy loves kicking," Brie added. "I actually was really nervous, because everyone's like, 'If you have a good baby, you're going to have a really bad one.' I was like, 'Well, Birdie was so good, so here comes my wild one.' He's calmer than what Birdie was."
