Little layers.
Cozy nights.
A simple place to start when choosing a sleep sack. Explore the room temperature, then find a TOG that suits your baby's needs.
How warm is the nursery?
Use a room thermometer for your actual reading. This slider does not measure temperature.
A versatile middle layer
NHS reference: 20–24°C (about 68–75°F)
Consider a 1.0 TOG sleep sack. Adjust the clothing underneath for your baby and the product's design, then check for overheating.
Explore 1.0 TOG stylesThe TOG guide, at a glance.
Higher TOG means more thermal insulation. Room temperature is only one part of the decision.
How to read this chart: NHS room-temperature guidance applies to the 0.5, 1.0 and 2.5 TOG rows. Boundaries overlap and individual layering matters. The 1.5 TOG row is a BubblePanda product option, not an NHS-assigned temperature range.
Three checks before bedtime.
More helpful than following a temperature chart alone.
Read the room
Measure the temperature where your baby sleeps rather than relying on the outdoor weather.
Consider every layer
Factor in pajamas, the sleep sack's TOG, sleeves and your baby's individual needs. Follow the garment instructions.
Check baby's chest
Feel the chest or back of the neck. If hot or sweaty, remove a clothing layer. Cool hands or feet alone are not a reliable guide.
A few little questions.
Does the NHS recommend a specific temperature for 1.5 TOG?+
No. The NHS publishes general bands for 0.5, 1.0 and 2.5 TOG commercial sleeping bags, but not a separate 1.5 TOG band. BubblePanda's 1.5 TOG collection includes long-sleeve styles, so the overall outfit needs to be considered.
Should I add a blanket when the room is cold?+
Not over a sleep sack. The Lullaby Trust advises adjusting suitable clothing layers or considering a higher-TOG sleeping bag if your baby feels cold. Avoid loose blankets and other soft objects in an infant's sleep space.
Is 72°F the only safe nursery temperature?+
No. There is no single temperature that guarantees safe sleep for every baby. Use the room temperature as a starting point, choose clothing and a suitable sleep sack, check for signs of overheating and follow established safer sleep practices.
