Sharing a room or not?

[MADMUMALERT]

Hi all just looking for opinions. I have a nearly 3 yo boy and 5 month baby girl. We have a tiny two bedroom house and baby is sleeping in my room with my partner and I. I have to return to work soon and was wondering if I should let the kids sleep in a room together. I put my son in his own room at 6 months. Im a bit nervous but as I work shirft work it would be difficult to keep her in my room.

Dd2 moved in with dd1 when she was 6 months ( dd1 was 3 and a half). Worked really well . A year later they still go to bed at the same time . Older one wakes slightly earlier so she comes into us. At the start we just went in to dream feed her and that didnt wake the older one.They are both excellent sleepers so that probably helped.
