@taarthi, I think I have the equivalent of a Master's degree in boxing things up. Surgery was one of the few times that focusing on the "now" instead of on the surgery made sense for me.
After freaking myself out about surgery details, I realized I didn't need to know any more of the medical side of it. My surgeon and his staff were experienced, I had completed dozens of tests, been cleared by many doctors, and approved for surgery by a donor board. Mayo is the best and I feel like they truly cared for (and about) me but really, if they didn't think it would work out for you and your husband, they wouldn't risk their reputation on a surgery that isn't likely to succeed.
Look how lucky you are at all the things you can focus on besides the surgery! I don't have as many details about the recipient side of things but I know a lot of things that Moms plan when they'll be off their routine for a while, especially during the holidays. Getting ready to go and preparing for help for a few weeks after you get back can occupy a lot of your brain, As helpful as your husband may be, he won't be able to lift more than 10# for 6 weeks. That means you may need a plan for shopping and any holiday prep you want done as well as cleaning and help with your child.
Someone in your family will probably get sick, it happens. My recipient had quite few infections that she didn't even know about until test results came in but the doctors were on top of it, they are on your side and want you to succeed. Every week will be different but every week will also get you closer to a new healthy life.
