Rose, that's a good way to look at it - that you're doing it for your son to give him a sibling. I suppose I don't think about how a sibling will be good for DD - just how it will shake up her world. But I'm sure it will be good for her in the long run.
I think DH is actually more excited than I am about the baby right now. When I was sharing my feelings I think he just wanted to make sure I'm actually ok, or if I needed, like, professional help or something, lol. He was being a little dramatic, because I was perfectly calm in what I was saying. I'm not that emotional of a person myself.
So this is crazy, but I only learned that what happened to me with DD's birth actually has a name - placenta accreta. No one ever used the term at the time that I can recall, but someone on a FB group mentioned it and after googling I was like "hey, that's what happened to me!" Placenta wouldn't detatch and the midwife had to manually scrape it out of me, then had to transfer to hospital, be put under, having the rest removed, have three bags of blood, and I was at "sustained risk of cardiac arrest" while I was under. So now this has kind of opened a door to re-examining everything that happened. Because now that I have been reading about it I'm learning how dangerous it is - usually if it's diagnosed during pregnancy the recommendation is to have a c-section and there's a high chance of hysterectomy if the placenta can't be removed and bleeding can't be stopped. My widwife from back then told me the chances of that happened again are very small, but it seems the chances are higher considering how they had to go in and remove it, so now I'm going to be worrying about that. I mentioned it briefly at my first appt at 5 weeks, but that was before I knew all this, so I'm going to have to bring it back up at my next one and see what they say about monitoring for it this time and if I'll be considered high-risk or not. Just kind of thrown for a loop that I'm just now learning more about this and it's been 2.5 years.
