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.
