We are in the process of looking at furniture for the nursery and space is at a premium. I actually whipped out the tape measure last night and THINK we'll be able to do the crib, a 6-drawer long dresser with changing pad on top, and a tall 5-drawer bureau (no closet space for LO really). This leaves little space for a glider, but we should be able to squeeze it into the corner between the crib and narrower dresser if we really need to.
I initially felt like having one was a non-negotiable, but upon further thought last night, I'm not so sure. We'll have LO in our room in a bassinet for the first 12 weeks or so and I'll likely nurse in bed at night, and probably on the couch watching TV during the day. I see it coming in most handy when LO moves to his/her own room and I can go in there to nurse without waking up DH. There's nowhere else to sit or lay down in the nursery, hence my original assumption we'd need it. And I certainly don't want to trudge downstairs 3-4 times/night to sit on the couch!
Did you guys find it to be necessary?
