... what did you do when #2 arrived?

LO #1 is almost 4 years old and still in bed with us. I doubt she will be moving to her own room any time soon (and we're fine with it, we don't want to rush her at all and want to wait until she's comfortable sleeping alone, whether that's age 4, 5, or 40. LOL). I'm planning on keeping LO #2 in our room for the first few months at least in a crib in our room, but would like to transition him/her out to their own room around 6 months.

But what happens if #1 is still sleeping w/us? Anyone else in this situation? Are we just gonna end up with another body in our bed? (thank God it's a king)
