What safety standard should a baby sleeping bag meet?
Short answer: Look for BS EN 16781:2018.
Here is the detail behind that answer, taken from current UK guidance from the NHS and the Lullaby Trust.
Things to check
- Choose the right size for your baby's weight so the neck and arm holes are snug and they cannot slip down inside.
- Pick a tog for your room temperature and adjust the clothing underneath.
- Avoid weighted sleeping bags, and do not use a hood or extra blankets on top.
What the guidance says
- Sleeping bags: look for BS EN 16781:2018.
- A well-fitted baby sleeping bag is an alternative to blankets. Most makers base suitability on weight (usually around 4kg) rather than age, so check the label.
