I CANNOT CONTROL THE FEELS RIGHT NOW I JUST CANNOT
Oh. What have you done to me?! *sobs* It just a short chapter you managed to take me through a roller coaster of emotions. At first, I was pleased about the baby. I expected it to be warm and fluffy and I just thought that it would be a happy story about the birth of their child and all the milestones they cross as parents.
Then I found it a little humourous; how Teddy was the one getting flustered while Victoire was going through labour, because usually it's the other way around. I still found the whole thing very sweet. I was actually smiling, but I could sense something going amiss. I don't know why, I just felt like something would happen, AND BAM. You dropped that bomb. I would never have imagined it in a million years. I actually stopped reading for a second to process what exactly happened, because I hadn't read the whole thing through. At first, I thought it was the son. That something was wrong with him, but that didn't feel right. As I read on, I felt more and more sad for Teddy. I can't imagine how hard it must be for him, to lose the love of his life, but still retain a piece of her through his child. I guess he'll have a tough time bringing him up without her help, but from how much you've given use here, I'm sure he'd make a loving, kind father. It is clear how much he loves his family. When he was begging and pleading to her dead form. I found myself wondering if there was truly nothing they could do. How utterly heartbreaking. Just. GAH.
I do have a few points of CC however. For me, I felt the whole thing was a little rushed. Everything happened pretty fast. I'd recommend fleshing it out a little by adding descriptions, with a special focus on emotions. This was emotionally heavy and the thought of having a child usually is, I suppose. So perhaps you could take us through how Teddy (and perhaps Victoire too) felt throughout the process? Maybe describe everything that has led upto this. Talk a little more about their love? (Though that would kick me harder in the feels now that I know what's going to happen :( ) I also thought that the process of childbirth could be a little more dragged out (without the gory details :p). Because here it seemed as if she went into labour, there was some nervousness, she reassured Teddy and they said it would take a little longer and suddenly the child was born. It was just very quick. You could also emphasise on his confusion when the healer came out, looking sad? It the emotions were more drawn out, this would be a lot more effective :)
Another thing I noticed was that Teddy was the only person in the hospital. Victoire comes from a big family and Harry practically fathered Teddy, so where were they during this vital moment? It just seemed odd that the Weasley family and even the Potters would be absent for an occasion as big as this. Surely at least Vic's immediate family and Andromeda, Harry, Molly and Arthur would show up? Let's not forget how Vic is the first grandchild on the Weasley side. They wouldn't want to miss the birth of her first born, would they?
And because I'm nitpcky and annoying, I have another point :p Please forgive me and ignore this point if you wish. It IS super, super nitpicky. Generally magical hospitals like Mungo's are for magical ailments. For something like childbirth, I suppose they'd have to go to a normal hospital? But this can be justified saying that by this time, wizards had set up hospitals in this field as well :p Also, when the child is born, I don't think they usher the father away? :p
Overall, I think you did a pretty good job. I ship Victoire and Teddy so hard and this was initially sweet, and eventually heartbreaking. Poor, poor Teddy! I can't fathom how he's going to cope now. I hope life is kind to him and their son, Christian :) Oh, and before I forget, I really thought that final interaction was very sweet. It was nice to see that the chapter ended on a hopeful note, even though it was so, so sad. A kick in a gut, but in a good way :) Nice work!
P.S- I probably should have seen it in the chapter name, but I really wasn't paying attention to THAT when I read this :p
