Toddler / newborn room sharing

La

Wondering if anyone has their kiddos sharing a room… and if it is successful? We just bought a new house and downsized from 4 bedrooms to 3 - I want the kids to have a playroom so I was thinking of having them share a bedroom. My son is 2.5 and daughter is 3 months. In future (maybe when my son is like 4/5) the playroom will become my sons room, but it is downstairs and I want to be sure I feel comfortable not having him in the same level. Would love to hear experiences!
