Did your newborn sleep in the nursery from the beginning? Did you co-sleep him/her in your room for a while? If so, how long were you able to do that?

I ask because I think we need to do some major HVAC work to our home...the previous owner split it into two zones each with its own unit. The master bedroom is one zone, and the rest of the house (upstairs and downstairs) is another zone. We want to redo it so either the entire second floor is linked to one unit, or split the bigger zone into two zones.

But to buy ourselves more time to save up for a project like that, we're hoping maybe once we have a LO they can sleep in the sitting room of our master bedroom for a while? How long can that go on realistically?
