Given your experience with how much time babies and toddlers pend in their own rooms, what would you do?

Here's our situation...

We have three rooms that could be the baby's room.

The largest is currently the guest room and has a five piece bedroom set including a sleigh bed and a two person bench. All of that furniture cannot fit in either of the smaller rooms. That room is painted a bright darkish teal and has minimal sunlight because we planted a bushy palm tree for privacy.

The other two rooms are the same size, get a lot of sunlight and we both work from home quite often. One room is my home office, which will have to remain intact somewhere. The other is my husband's dedicated space and can be dismantled- love seat & chair given to charity and guitars housed elsewhere. Both of those rooms are painted a light gray.

Here are the options I have thought about so far and I'm open to other solutions.

One: keep guest room as-is, use one of the smaller two rooms as a nursery, and keep the other as an office. (Easiest option).

Two: give baby the larger room, which will be great for sleeping & playing esp as baby gets older, make one of the smaller rooms the guest room (furniture reduction), keep the other small room as an office. (If we have baby #2 this set up will be quickest transition for room sharing)

Three: make the larger room a home office & play area for the baby, make one of the smaller rooms a guest room and the other smaller room a nursery.

Other play space would just be our family room.
