My vote for your first To Do is to get B's birth certificate so that it won't hold you back in case you want to travel.
Your "30" list ought to be filled with the things that will give you the most peace and satisfaction with never being able to go back to your 20s ever, ever again. Think of yourself as a 30-year-old, then think of the things you'll want to say you did before you turned 30. Stick a few things on there that might feel unrealistic. You never know when an opportunity will come up to do them, and having them on your list will give you that extra motivation to do them when you find yourself making a bunch of silly, boring excuses not to.
