Many girls on my birth month board have already set up their cribs and putting together the nursery. The range would be 20-24 weeks.
I have one picked out but we haven't purchased it yet. I wasn't planning on putting it together until late May (~29 wks) We have bedding and other nursery items already but nothing is out.
Curious to see how far along you were when you put together the crib in the room.
