Alec hands Raphael to Magnus and gets out of bed, rushing to see if his sister is okay. "Izzy? Hey what's wrong? Are you hurt? Is everyone else okay?" She shakes her head and tackles him into a hug, crying into his chest. "My bwover..." Alec freezes. He lifts her into his arms and takes her to the living room, letting her sit in his lap.
"How old are you, sweetie?" He's using the gentlest voice he can, like when he talks to Raphael. She holds up her index finger only, her middle finger moving to show that she's between 1 and 2 years. Alec pushes her hair out of her face and just smiles at her, not wanting to scare her when she's upset and vulnerable.
"You're just a little girl, huh?" She smiles a bit. "Did seeing me take care of another baby make you upset?" She nods and hugs Alec. "My Awec..." He can hear the tears in her voice. Alec rubs her back and holds her close. He feels her raise the slightest bit off of his thigh and sees the change in her underwear. He turns to see Magnus watching them, Raphael on his hip.
"Thought it would be a smart idea." Alec nods. "Thanks." Izzy looks at Alec and pokes his cheek. He puffs it out, making her laugh. "How long have you been little? Can you answer that for me?" "Long time... Ol' daddy no love me... I be little 'lone..." "Was your old daddy Meliorn?" She nods sadly. Alec holds her closer. "I'm sorry that you had to take care of yourself alone." Izzy just cuddles into Alec. The older Lightwood starts to braid his sister's hair, impressing Magnus by how well he does it. She smiles at the little ribbon that Alec tied the end into. "Tank you!" Alec kisses her head and keeps her close to him. Magnus rests a hand on Alec's shoulder.
"I am willing to take her in if you are." "Mags I can't just leave her... She's my little sister and I didn't know that she was doing this on her own since her and Meliorn broke up... I really want to." Magnus nods and Raphael pats Izzy's head gently, trying to be a comfort. Izzy giggles and holds Raphael's hand. He giggles and Alec smiles at the fact that they seem like they will get along. Alec makes Izzy look at him.
"Would you like Magnus and I to take care of you? I would love to do this and Magnus said yes too." Izzy nods and cuddles into Alec, letting go of Raphael's hand. Magnus smiles and places Raphael on the floor, snapping up a blanket and some toys so that he's occupied while they get Izzy settled in. Raphael is content with this as Magnus gets a onesie that looks like a kitten to put on Izzy. Alec changes her in it and takes her makeup off, not wanting it to smudge onto things. Alec keeps her in his lap as Magnus grabs a bottle.
"It has a milk based meal replacement in it, figured that would be calming for her." Magnus hands the bottle to Alec and he gets Izzy to latch onto it very easily. She rests her head on her brother's chest and drinks it slowly. Raphael watches and lets his papa hold him. Magnus can see that he's closer to normal headspace now and kisses his head. Raphael smiles and just watches Izzy get fed.
"Cutie." "Yes she is a cutie. Are you alright with this, Raph?" The Little nods and keeps watching Izzy drink. Once she finishes, Alec makes sure she burps before she gets comfortable again in Alec's lap. The older shadowhunter sat on the floor with his sister and makes sure she can reach toys perfectly fine.
After about an hour of them playing, Izzy starts to whine a bit. Alec looks at her with concern. "Something wrong, kitten?" Izzy just whines again, she's not very verbal when she's Little they've noticed. Raphael crawls over to her and holds his hand out to her, offering comfort. She crawls out of Alec's lap and closer to Raphael. Izzy crawls over to Raphael and sits beside him. As soon as her padded butt touches the floor, Raphael smells it. He looks at Izzy and wrinkles his nose.
"Papa, Daddy. Izzy stinky." The Little shadowhunter sticks her tongue out at Raphael as Magnus snaps off her onesie, putting her into one of Alec's T-shirts instead since she isn't wearing a bra and wouldn't be comfortable with her breasts hanging out. Alec pulls back the waistband of her diaper and sure enough, it's very full. Given that she sat down on it, her mess has spread and strengthened the smell. Magnus wafts it away and Alec chuckles softly.
"Well at least that should put an end to her stomach issues the past two days. This better show her to just give up cooking." Magnus laughs a bit and snaps up what Alec will need to change her. "Darling it is admirable how that foul odor does nothing to you." "I've been around worse, it doesn't bother me." He tickles Izzy's belly as he lies her down on the mat Magnus put down, making her laugh. Magnus picks up Raphael and takes him to the other side of the room.
"I want to spare both of our noses." Alec laughs and opens the tapes of Izzy's diaper. He rubs his nose against Izzy's, making her laugh and distracting her as he starts to wipe her clean. Once he cleans, powders, and tapes her into a clean diaper, he kisses her forehead and pulls her into a hug.
"See? That wasn't so bad now, was it?" Izzy shakes her head and giggles as Alec gives her tiny kisses on her face. Magnus smiles, snapping away the dirty diaper and sitting beside his boyfriend with both Littles in their arms.
