Hi!

My son has severe Hemophilia B. We have an intense story, but everything is OK now. He had a head bleed and emergency brain surgery two years ago. But head bleeds are very rare for moderate hemophilia, and they're even rare for severes.
Since his head bleed, he's been on twice-weekly prophylactic infusion of replacement factor. We started doing the infusions ourselves, because he's a hard stick and I was more successful than the nurses were. That's sometimes been hard on us, just because when we have hard infusions, where we can't get his veins, it really affects all of us. But for many, many people, infusions at home are easy.
With moderate hemophilia, you'll really have to wait to see what his bleeding pattern is. Some moderates bleed more like severes, and in that case you may want him to go on prophylactic infusions. But most moderates just need occasional on-demand infusions, in response to an injury, etc. And you're absolutely right that you need a medicalert bracelet. Sometimes moderates get joint bleeds, which is something you'll need to watch out for. My son has had a bunch of joint bleeds as he's gotten older, but in the early years there were not very many. I would say that this first year is the time that you can relax a bit and research, find a hematologist you like, etc. The toddler years may be more challenging.
My son is also very very happy, and loves life and lots of activities. He just told his new first grade class all about his hemophilia today, and didn't want any help from me. He's doing great. I'm so lucky to be his mom.
I'm glad to meet you! It's always helpful to talk to other parents. So, hello to you and your precious little guy!
