So, I hope you like it!

Jace: When you told Jace that you were pregnant, he couldn't be any happier. You'd still go on missions with him, but he'd always keep an eye on you, making sure nothing happened. When there was a big attack and everyone had to defend themselves, he'd often do it for you, not wanting you to get tired. He'd also, at the very end of your pregnancy, buy several things from ikea and grew grumpy whenever he'd got it wrong, trying to get some furniture for the baby's room ready.

Alec: he would get all worried about you, telling you you couldn't drink alcohol, consume a particular amount of greasy food and he'd make you tea. For some strange reason. Than he'd read books on how to best treat a pregnant lady and get even more worried, thinking he was doing it all wrong. Once you told him he was perfect the way he was, he got a bit more lose, and even gave you a glass of wine one night.

Magnus: of course, Magnus had already raised a few children, but never one of his own. He'd make a whole extra room for the baby and he would treat you like a princess, giving you ice-cream, making you food and even keeping up with you thinking about names for the baby. He was so over the moon that he got a little over protective once you got a "belly" and didn't want you to go on missions anymore, or visit hotel Dumort.

Simon: he was quite stressed at first and grew a lot more careful about what he said once you lashed out at him for no reason whatsoever. He let you do all the normal things, except doing activities requiring energy and speed, as running or walking long distances. He'd drive you everywhere, and asked you to be careful wherever you went. But for the rest, he was very calm and easy-going.

Raphael: well. He never expected to have a child, so once you told him, he didn't want it to be raised in Hotel Dumort. He tried getting his own place, figuring a way to walk in the sun by buying a ring from Magnus that was filled with magic grantin him the ability to not only stay hidden in the dark. He got a whole room for the baby, painted and everything. He didn't treat you much differently, just more gently and calm. He wouldn't mind you screaming at him or vomiting anywhere, but once you're pregnancy was almost to a full seven months, he did everything from cooking to washing the dishes.

Sebastian: he cooked for you, as often as he could. He went to the shops daily to get you something nice, like flowers. Even in the middle of the night, when you wanted something strange to eat, he'd go through all of New York for you to find it. Once you became less mobile because of your "belly" he even did all the other things. But up to the moment of that, you went on mission and everything. He didn't want you to feel like being pregnant made you unable to do what you liked, he just tented to come with you more because he wanted to guard you without you noticing too much.
