Baby Sleep Sack TOG Guide (Plain English)

Quick answer

TOG measures sleep-sack warmth. Higher is warmer. Match TOG to room temperature first, then confirm on the chest.

  • 0.2–0.5 TOG: warm rooms (~24°C+)
  • 1.0 TOG: typical nurseries (~20–23°C)
  • 2.5 TOG: cooler rooms (~16–19°C)

TOG without the jargon

TOG is a warmth label. TinyLayers leads with plain-English layers, then shows TOG as a helper. It never recommends 4.0 TOG.

This is general dressing guidance, not medical advice. Every baby is different — for fever, premature birth, or any medical concern, follow your clinician.

Frequently asked questions

Is a higher TOG always safer in winter?

No. Overheating is the documented risk. When torn, go lighter and re-check the chest.
