When did (or will) you move DC to his/her own room? Why that age and not sooner or later?
When my niece was born, SIL only had a one-bedroom apartment, so they had to share a room. When SIL moved here from San Jose, she moved into a 2-bedroom apartment so now niece has her own room. That's just how it worked out.
We are actually planning on doing it this weekend...but I am not looking forward to it.
I wish I would have done it around 2 months, when I had originally planned to...but I am a procrastinator and I think it will be harder now.
