Also really focus on learning boundaries. If she's not old enough to grasp the rules of the baby room (we don't climb on our friends) then, in my opinion, she's not old enough to move up.
Basically, if she's bored and the room is meant for children her age (which is sounds like it is) then there need to activities offered that engage her.
This ^^^^ age is nothing but a number and her size should never play a role in anything (other than being carried etc).
I've seen a lot of larger kids be treated older simply because they are bigger (physically but not cognitively or developmentally)
I also agree that her behavior is a clue to the environment.
If she acts bored, its more than likely not her needing to be moved it's that the toys/activities aren't engaging enough for her.
