What do you do/are you going to do when they get too old for it? I use the arms-reach mini co-sleeper, and it works out very well. My son is 2 1/2 mos. old now and we have used it about 95% of the time since he was born. We occasionally put him in with us, but we're not small people and a queen sized bed is pretty crowded already. I was wondering what you guys do when they get too big for it?
