Back to the Crib

After a week of sleeping on a "big boy bed" (translation: crib mattress on the floor) and doing great with the transitional set-up, I asked William if he wanted to helps take apart the crib. He immediately tells me "my mattress is supposed to be in here (pointing to the crib). Put it in its regular place where I sleep." After several questions seeking to confirm this request, I returned the mattress to "its regular place" and William returned to his crib "where he's supposed to sleep" this evening.
