My child has outgrown their toddler pillow
The arithmetic is the same at any size: required loft is neck-to-shoulder minus mattress sink. Children simply have smaller values for both, and — the part that catches people out — the numbers move as they grow, so a pillow that fitted last year can be genuinely too flat now. There is no age at which a child needs a particular height; there is only a measurement.
This one is not a pillow question alone. Safe sleep for babies and young children is governed by paediatric guidance — including at what age a pillow is appropriate at all — and that guidance overrides everything here without exception. This page describes only the geometry of pillow height and makes no recommendation about infant sleep.
What the pillow has to do
- loft in measured range — Pillow loft within the range your own measurement implies. This is first for every constraint in this cluster, because no surface is soft enough to rescue a pillow your head has already flattened.
- adjustability preferred — A pillow whose height you can change, because the thing altering your geometry is not present every night — one fixed height cannot be right both with and without it.
