Baby room/Nursery ideas

Moved recently and fortunately we are able to have separate rooms for sleep and play, especially now that baby 2 is on the way and we've just started to get baby 1 out of our bedroom. The playroom is colorful and a little chaotic, so before you call me a sad beige mom, bear in mind this room is exclusively used for naps and overnight sleep.

Our house is too small to have a dedicated nursery and I wondered if others have done this and how you have managed it? We have a room but it will also likely have a spare bed, dressing table and husbands office set up in there. Baby will sleep next to us but what do we need in the other room to make it work for us and baby? Any help please?!?!

I help with design

We are renters and our condo is quite small and dated (due for new carpet, still has popcorn ceilings etc.), but we worked with what we've got! There is actually wallpaper we ordered, but we will only be living here with the baby for about a month before we move, so I chose a paint color that matched closely with the wallpaper we will ultimately be using.
