Baby sleeping bag buying checklist

• 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

• 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.
• The Lullaby Trust does not publish a tog chart, because fabrics, layers and babies differ. Use the room temperature as a guide and check your baby's chest or neck.
• Avoid weighted swaddles, weighted blankets, weighted sleeping bags and sheepskins.
• Sleeping bags: look for BS EN 16781:2018.
