My son will be nearly 3 when baby #2 arrives, he sleeps in the middle of our king size bed (which is just a memory foam mattress on the floor, no box spring, no frame), and pretty much sleeps through the night.
We intend to let him transition to his room when he is ready, but I'm curious how the arrival of more children affected your sleeping arrangements.
Did you have something like an arms reach co sleeper for the baby until s/he was big enough to be in the big bed? Did your oldest have any issues with being woken up by the baby?
We still have several months to go, but I just want to know the logistics of what I'm trying to do. I know several people that cosleep with both their kids but they are older. My son can be a bit of a thrasher at night so I know we will have to have the kids separated to some extent, tell me how you did it!
