I'm watching this thread because just last night DH asked when Jelly Bean is going to start sleeping in her own bed instead of ours. (In fairness to him, he's a very light sleeper, so her sleeping in our bed means he's sleeping in the guest room every night.)
But I think you know the answer to your first question, OP. Don't worry about what you'll do when the next one comes along, because chances are, you'll be able to have that baby sleep in the crib just like this one did.
I'm in your situation. . . Jelly Bean slept great on her own until Ha was two weeks old and we had a week of nightly thunderstorms. She woke up scared; I brought her to bed. . . and she's napping there right now! But even in my bed, she wakes up crying in the middle of the night fairly frequently, and other posters' suggestions of deciding in advance how to deal with that makes a lot of sense to me.
