Author's Notes: So as the summary says this will be a collection of one-shots written by myself that center around the childhood of the Lightwood children. I have a handful planned out and I'm open to suggestions.

It's A Girl:

"Alec dear, are you ready to have a baby brother or sister?" Maryse leaned down to look into her son's blue eyes. The two year old continued to play with a train set he had gotten for his birthday; he didn't seem to notice his mother standing beside him, one hand on her enlarged stomach. Maryse stood up and winced, pain flaring up in her back. She moved to sit in one of the chairs in the library, watching Alec play on the floor. She hoped he would be excited about a sibling, someone he could play with, and eventually train with. Maryse heard the door open and her husband emerged from the hall, Church lazily stretched out on the floor behind him like someone had just scratched his belly. Robert stooped to ruffle Alec's hair before coming to stand before his wife.

"How is everything?" His gaze lingered on her stomach but quickly moving else where; his hand rested on the armrest.

"It's been kicking, nothing to worry about." Maryse wound her fingers through his, feeling the tension held in the joints. Ever since she had told him they were going to be parents again he had become more tense, distant. A faint ghost of a smile played on his lips before disappearing at soon as it had appeared. A strained silence followed.

"I have work t do." Robert pulled his hand away from his wife's, turning to face the library doors. Maryse didn't know if it was the hormones or something else but she was at the end of her last nerve.

"Robert Lightwood, ever since I told you I was pregnant you've been finding every possible way to stay locked away in your office. I've had enough!" She stood and stepped in front of him. "What is it? Do you not want another child? Can't handle the one you have? Or is there something else?" She pointed an accusing finger at Robert who had manoeuvred around her and was once again making his way to the doors.

"Maryse you know that's not true. I love you and Alec, and I'd love to have a bigger family, it's just..." He could see that Alec had stopped playing and was watching them. "I don't have time for this." Robert pushed the door open, letting it slam behind him. The door to the study could be heard slamming as well, locking him out from his family. Maryse stood quietly, letting the tears leak down her face.

Later that night when Alec was tucked in bed and Robert hadn't yet ventured from his study, Maryse lay in bed unable to sleep. She rolled onto her side, one hand across her stomach as she watched the time tick by. When her eyelids finally grew heavy and sleep was coming around she realized that someone else had other plans that didn't involve a good night's rest. Sitting up the best she could Maryse could feel the sheets dampening beneath her.

"Robert!" Her cry went unnoticed. "Robert it's time! The baby's coming!" The sound of footsteps coming down the hall seconds before the bedroom door burst open reassured her that Robert was here for her.

Alec waited in the library with Hodge watching over him, his parents were in a room down the hall. Pain filled wails could be heard coming from behind the door he had been told not to enter. Hodge rubbed small circles on Alec's back every time he flinched.

"Soon you will be a big brother, Alexander." The older man spoke in a soft tone. Alec continued to look at the doors that separated him from his family. After countless cries a new sound greeted their ears and Robert poked his head around the door.

"Alec, would you like to come see your baby sister?"
