- One word, three letters: SEX -

Andy and Robert had previously made the joint decision that they didn't want to learn the sex of their baby until the birth. They both knew that regardless of whether the baby was a boy or a girl, they were going to love this child with all their hearts and so would everyone else. They knew that whether this child was a boy or a girl, that he or she was going to be cherished. But the real reason was that Andy was adamant that they should not tempt fate. So together they decided to keep the sex of the baby a secret.

Given their steadfast resolution to not know the sex of their baby, it was hard to explain why Robert and Andy were sitting in the car staring at the ultrasound picture debating if their baby was a boy or a girl.

"She is definitely a girl," declared a glowing Robert as he continued to stare at the picture in Andy's hands. He could already imagine his daughter being the spitting image of his wife, right down to her gorgeous dark waves being held back by a headband.

"No, this baby is a boy," argued Andy as she touched her small, but now visible bump. She was convinced the baby was a boy and couldn't wait to see how much he would resemble her husband. "I mean, look at this picture. Our baby has three legs!"

"What can I say, he's a Sullivan," Robert joked. He then quickly raised his hands to protect himself from his wife's blow.

"Robert!" she screeched but she relented as she realized what he said. "But at least you agree with me now and acknowledge that our baby is a boy."

"No, no, no. I did no such thing!"

"Yes you did. I heard you with my own ears," Andy gloated, as the grin she was sporting got even larger. "There is no denying that we are having a baby boy Sullivan in twenty weeks."

"I disagree," Robert responded snidely, and then he got an idea that he knew Andy would never be able to refuse. "But if you are so certain that our baby is going to be a boy, then you won't mind a little wager."

"I'm listening," she answered cautiously and she couldn't ignore the rush of excitement flush over her.

"If you're right, and our baby is indeed a boy, then you can have the privilege of naming him," and Robert could already see Andy's eyes brighten in anticipation. For weeks, they had argued about names for their unborn child and they could never agree. Andy dismissed all the names Robert recommended, and he was adamant a Sullivan would never have any of the names she suggested. They were at a standstill.

Robert then took great pleasure in bursting Andy's happy bubble by continuing, "However, if our baby is a girl, then I will have the great honor of bestowing our child with the name she will have for her entire life." And just as he expected, Andy's face immediately deflated when hearing the other half of the wager.

"So, what do you say?" Robert teased. "Do we have a deal?"

Robert held his hand out to Andy and waited to see if she would accept his conditions. But he knew deep down there was no way she would refuse his challenge. After all, they still loved the game.

Andy then extended her hand and stated, "Deal."

- One word, three letters: BOY -

Andy was seated in a wheelchair as she reluctantly released her hold on their baby to Robert so that he could place the child in the car-seat. Once that all-important task was completed, he returned to Andy's side and helped her into the backseat of the car.

Moments later, the Sullivan family - all three of them - were on their way home.

"He's absolutely perfect, isn't he Robert?" a beaming Andy commented never taking her eyes off her son.

"Of course, he is – he's half Herrera and half Sullivan," Robert joked before turning more serious. "I still can't believe he's ours."

"I know," Andy agreed with a huge smile on her face. "I feel like I've been living in a dream for the past 48 hours."

"I will never forget Carina's voice when she said, 'It's a boy!'"

Andy heart filled with so much happiness. Just a few years earlier, she never would have imagined this would be her life. But here she was, bringing her beautiful, healthy baby boy home from the hospital with her loving husband by her side. Perfection.

"I love you Robert," Andy whispered as she enjoyed the moment.

Robert turned back to look at his wife and the baby in the car-seat next to her, "I love you too, Andy." After glancing at his son and then Andy, he quickly added, "Thank you."

Throughout their lives together, three more 'three letter' words would become part of their everyday language. That would be MOM, DAD, and SON.
