It's anodized aluminum bodyy is not a soft material, but for around 20-25$ you could get her an L3 Illuminations L10 twisty model, available as a 4 mode (with firefly) or a 3 mode (low, med, high, no firefly) in either cool white or the high CRI neutral white Nichia 219B (High CRI, for the children!)
-with <5 minutes of patience and some marine grade heat shrink tubing, a lighter, and a razor blade, you could make the entire aluminum body become covered in bite friendly plastic.
-The L3 L10 4 mode Nichia is a phenomenal light for the price, quality, form factor, run times, and battery.
I would have Loved to have one as a youth.
-also, as a 4 mode light, with firefly, it's at least 2x-4x nicer than a mere 3 mode, besides, kids have great night vision and can really benefit from firefly mode, and they'll bother you for fresh batteries a lot less often as well.
