There's a particular kind of stocking filler that actually earns its place at the end of the bed: not a five-second novelty, but something that keeps a child quietly absorbed whilst the rest of the house wakes up around them. Small enough to fit in a stocking, substantial enough to still be going strong come the Boxing Day lull. Plastic-free, gift-ready in its own tin or packet, & good enough to actually finish before the wrapping paper's cleared away.
