Using the Nursery

Alyssa • Single Mother of Two.
With my first son, the way our living situation was, we shared a room with him until he was two. He was in a pack-n-play bassinet until about 5 months and then moved to a crib. This time around we actually have a nursery. I plan to have him in our room so he's close by in the early months for the frequent wake-ups. But I'm worried I'll be too nervous to switch him to the nursery even when he's ready. When do you typically place them in the nursery?
