This is one idea for how Nick and Adalind could have added another baby.

Nick smiled warmly as he tucked his children into bed. It had been a day filled with fun, and the kids had worn themselves out playing. The whole family had gone to a local beach, joined up with Monroe and Rosalee's family, as well as some eisbiber families, for a day of running, hiking, swimming and enjoying all the food brought for their picnic.

The triplets were old enough to run around on their own, and had certainly done their share of wearing out the adults.

But there were still a couple of infants at the picnic. Bud's relatives, Nick can't remember how they were related, had brought their infant daughter.

Adalind had asked to take a turn holding the baby. Nick felt a twinge in his chest, when he had seen her cradle the child in her arms. A tender smile spread on her face as she held the baby close to her.

Nick also sensed a bit of longing. That's when he realized that Adalind wanted to have another baby.

In truth, there had been many times when he had thought about bringing the topic up. Nick loved Kelly and Diana with all of his heart, but, he still felt there was room left for another.

Nick also wanted he and Adalind to have a child that was planned. One conceived out of choice.

He made the decision to talk to her about it that night, when they were alone in their bedroom.

But talking became impossible when he saw Adalind was waiting for him, wearing a sexy white negligee.

"I want to ask you something." She said. "And promise, you will at least think about it." She took a deep breathe. Which was very distracting for Nick, since it lifted her breasts. "I would like to have another child. I know that with Diana and Kelly, we already have a lot to worry about. Diana being so powerful and Kelly could become a grimm, or a zauberbiest or a mixture of the two, but, I know we could handle another. We're good parents, and our kids are wonderful, I think that we'll be able to handle a third." She looks up at him pleadingly, "Just promise me you'll think about it."

"There's nothing to think about." Nick says, pouncing on her, his body weight forcing her flat on the bed, covering her form with his own, "You're getting pregnant tonight."

Adalind's giggle of delight is muffled by Nick's mouth on her's.

The very next day, Adalind was smiling to herself, thinking of the night before and the possibility of having already conceived, when Diana walks up to her, and slowly places her hand on Adalind's stomach.

"Mom, you're going to have another baby. Another one like dad Nick."

Knowing better than to question her daughter's powers, Adalind smile widens and she places both of her hands over her still flat belly. She closes her eyes and imagines for a moment, picturing that little life just starting to grow inside of her.

Then, it strikes Adalind that her oldest may not feel like this baby is a good thing. "Diana, you know that this baby won't change how much Nick and I love you, right?"

"I know mom." The little girl says matter of factly. "You and dad wanted a chance to do everything right. From the very beginning. You wanted to share everything, together."

Adalind was relieved to hear her daughter accepted the new baby so quickly. And a little shocked to hear the child understood completely what the couple had wanted.

Though, nothing should surprise her anymore. Her children were remarkable.

Still, ever the thoughtful mother, Adalind asks her daughter. "How does me having another baby make you feel?"

"I'm happy mom." Diana replies. "I'm really excited to be getting a little sister."

"It's a girl!" Adalind gasps in shock.

The moment Nick got home, his wife was waiting for him with a huge smile on her face.

She throws her arms around him, hugging him tight and planting a whopper of a kiss to his lips. Then, pulling away from him, she excitedly asks him, "Do you remember how Diana knew that Monroe and Rosalee were having triplets?"

Nick guesses what this is about, but Adalind doesn't give him enough time to respond.

"Diana says I'm already pregnant and that it's going to be a girl!"

Nick lights up and pulls Adalind in tightly for another hug. He peppers kisses all over her face and down her neck. He buries his head there, breathing in her scent, basking in the joy of expanding his family with her, his beautiful, brilliant, amazing, miraculous wife.
