Extended room/bed sharing with baby?

Ma

Have any of you shared a room with a baby beyond 3 months. We moved June baby to his own room at 3 months when he started rolling in the bassinet.

What was your experience sharing a room for longer or bed? Or can a 2 year old and an infant share a room with out disturbing each other?

I am trying to plan for baby #2 (due in June) Our original plan was to create a big boy room in the spare bedroom/office for June baby #1 but that is no longer an option right now.
