Hey ladies... wondering if any moms on here have already had your second and might have an opinion or experience to share.

What's the best rooming arrangement for a toddler and infant? We have a 3 bedroom house. Currently our toddler has her own room and the spare bedroom is an office/catch-all. #2 is due in April. Should we...

1) Set up a nursery and let our toddler keep her room?

2) Make one room a play room and then have the kids share the other room for sleep once baby is grown out of the cosleeper? Or

3) Is it fine to have them share a room and keep our spare bedroom as an office?
