White noise for toddlers: keeping the sleep cue when you move to a big bed

General information, not medical advice. Talk to your paediatrician about your baby’s sleep and hearing.

A big-bed move is a big change. Keeping one familiar thing — the same sound, at the same low volume — can make the rest feel less new. The same rules that apply to babies apply here: quiet, far, and on a timer.

Keep what worked

• Use the same sound your toddler already knows.
• Keep the same routine in the same order: bath, pajamas, book, song, lights down.
• Place the speaker across the room, not on the bed or the bedside table within reach of small hands.
• Use a timer with a fade-out rather than leaving the sound on all night.

Let your toddler have a say

Toddlers love choices. Let your child pick between two sounds at bedtime — fan or rain, for example — then stick with that choice for the week. Choosing gives a sense of control, and the sound still works as a cue.

Plan for the move

1. Keep the same sound in the new bed and room for the first week.
2. Do not change the routine on the same day as the bed.
3. Expect a few bumpy nights and respond calmly and consistently.
4. When you are ready to phase the sound out, see how to wean off.

A toddler's hearing is still developing: keep the level near the quiet-conversation mark (safe-volume guide).
