5yo dd1 is miserable this evening because she feels as though her bed is moving. She says it's tilting like a swing. She particularly hates swings, as she overperceives movement in any case so I imagine this is really horrible for her.
Does anyone have any idea what it could be and what I can do to help her? Might it be an inner ear thing? It isn't constant, just keeps happening occasionally. She thought it might help to be propped up rather than lying flat, but then it happened again.
