There are only two things you need to know.
You will never feel like you know what you are doing, unless
Someone tries to tell you how to do it at which point you discover, never tell someone how to raise their kids.
Good luck, get lots of sleep, and remember, the child will never be anything other than what you raise, so, if in 18 years you hate the person, hey, YOU raised that person, it WILL be your fault 🙂
