Is a weighted sleeping bag safe?
Short answer: No. The Lullaby Trust lists weighted sleeping bags, swaddles and blankets as products to avoid.
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
- Avoid weighted swaddles, weighted blankets, weighted sleeping bags and sheepskins.
