I think you’ve done well with the concept! Solid history without being too ornate, lots of open room for development and questions answered, and sounds like you’ve already got ideas about how to highlight with mechanics.
The only piece of advice I would give is, in addition to thinking about leaving hooks open for the DM to work into the story, also consider the other direction: how is your character going to be moved, compelled, and changed by the broad strokes of the adventure they are going to get into and the companions they are going to be adventuring with? How can this character help set up other characters to do “their thing”? I’ve found the games I’ve played in to only be improved by having those dialogues with the DM and other players up front







Congratulations! It’s an exciting time and they are such marvellous little creatures. Here are some random thoughts that may be useful
Pregnancy
Delivery
Most hospitals / maternity wards offer tours. If you are planning a hospital birth, going in the week before to see the place helped reduce a lot of the anxiety when the time finally came. They can’t be scheduled far in advance because it depends on how busy they are, so keep checking
Familiarise yourself with the physical details of the birth process. We read through “The Birth Partner” (Simkin and Cheney) together in the preceding months. There is one chapter where they subtly endorse some pseudoscience, but if you can skip over that when you run into it, we found it very informative and helpful about what to expect.
The event itself is exciting, but overwhelming. Again, your wife will be entirely consumed by managing the physical demands. You can help by taking care of the logistical and emotional demands. Advocate for her. The staff are on the same team as you, but you are the only one with the brain space to ensure that the decisions your wife wants for the birth are being kept in mind.
Newborn
The first 2-3 weeks are the hardest. You’re adjusting, and the baby is adjusting, and all three of you will have to figure out how to make it work. I hope you are in a place where you can all take time off work. We were lucky in that we were able to breastfeed without too many issues, but regardless if it works the same for you or not, those early days must be a team effort. My wife fed, I did the diapers, and we all woke up together.
Early on, we ran into some pretty difficult nights where the baby just would not sleep. It turned out she was not getting enough breast milk. Once we started adding some formula, she went right back to sleep. We did this until my wife’s supply increased, which is a fairly common pattern.
I don’t know why I didn’t expect this, but newborns generally dislike the experience of getting their diapers changed. It will be a fight for a little while. I say this because, if they ever stop crying while you are in the middle of one, duck and cover. That means they are about ready for part two. And it can come with some force. Those little changing mats do not cover nearly enough. We had to put down an extra layer of paper towels along the whole “trajectory”. (This does calm down eventually)
Babies are demanding. It is rewarding, but there will be exhausting days. Early on, my wife and I devised a system where we each get one day a week that we have “off” from the baby, barring emergencies. I can’t overstate how much of a difference having that one “recharge” day makes in managing the stress, it has been extremely helpful.
Things we got that have been worth their weight in gold:
Things we got that really weren’t as important as we thought they were going to be
I know that looks like a lot, but it’s really not bad, because most of it is extra, conveniences and nice-to-have things. As long as you have food, diapers, and a safe place for the baby to sleep, all of that other stuff can be figured out on the go, and you will figure it out as you find what works for you. And the love and joy that come with the baby are indescribable. The rewards are there, and they eclipse the challenges.
You can do this, and it will be wonderful!
