What it helps with
Twenty minutes to wrap. Two seconds to undo. Nappy needed.
Origami with a muslin at 3am, then starting again after every nappy.
Zip up, done. Arms stay snug, hands where they like them.
How to use
- Lay them in, arms by their sides or up by their face, whichever they prefer.
- Zip up from the feet. The roomy bottom leaves their hips free to bend.
- For nappy changes, unzip, change and zip back up.
Safety & honest notes
- Stop swaddling as soon as your baby shows signs of trying to roll. That's the Lullaby Trust's advice, and ours.
- Always on their back, never over the head, and don't pile blankets on top. It's a light layer; check they aren't too warm.

Questions
Asked by parents like you.
Something else? Ask a real person. We reply within one working day.
When do we move on from it?
When they start trying to roll, or by around 3–4 months at the latest. Then a sleep bag with their arms out: our Stay-On Sleep Bag 2.5 Tog is the next step.
Is delivery really free?
Yes. Every order ships free across the UK in 2–4 working days, with no minimum spend. Next-day delivery is £4.95.
What if it doesn't work for us?
You have 60 nights to try it at home. If it doesn't help, send it back for a refund. Feeding and hygiene items need to be unopened.
