This is absolutely great news.
Take lots of pics and videos all through the pregnancy. My 4 yr old daughters favorite past time is watching home movies, even before she was born.
One bit of advice: Things get tense until the baby gets somewhat self sufficient, just keep in mind there is light at the end of the tunnel, and no matter how much you do it will never be enough. Just take it with a grain of salt, because nothing puts you on edge more than sleep depravation.
Good luck.
