How would you decorate?

P

Baby number 1 is 2, will be 2.5 when her sibling is born. They’ll end up sharing a room between 3/3.5 regardless of the sex of baby 2 (we’re not finding out).

Currently her room is boring (white walls, curtains match the carpet etc) so want to get her some things she could move with her into her new room when they share.

What could I get for her room/decorate with that would go for a girl girl room or girl boy room?

Thank you!
