Arm poppers on ergoPouch swaddle sleep sacks: safety reports

Are the arm press-studs on ergoPouch swaddle sleep sacks a safety risk for a baby?

ergoPouch ErgoCocoon Swaddle Bag: Across parent forum threads the press-stud arm conversion is the most praised feature, especially for babies who rolled earlier than expected. Several parents report the bag creeping up so fabric covers the baby's face when the arms are swaddled in, and some call this a suffocation risk; the same reviewers generally say arms-out mode is fine. ergoPouch Cocoon Swaddle Sack (also sold as ErgoCocoon Swaddle Bag): Across community threads the press-stud system allowing both arms-in and arms-out is the most praised feature, especially for babies who roll early, because the chest stays snug even with the arm holes open. Several parents who say they used the correct size report the swaddle creeping up over the baby's face with the arms in; one says they only noticed because they checked in the night and calls it a suffocation risk. ergoPouch Cocoon Swaddle Sack (Berries print): Across community threads the press-stud system that allows both arm positions is the most praised feature, especially for babies who roll early. Reports that the bag creeps up over the baby's face during the night, even in what parents believed was the correct size, appear several times, and two parents describe it as a suffocation risk. ergoPouch ErgoCocoon Swaddle Bag (lovemedobaby.com): Shoulder studs let the swaddle change to arms-out sleeping as the startle reflex fades. Several parents report that the fabric rides up over the baby's face when the arms are enclosed, even in the recommended size, and describe it as a suffocation risk. ergoPouch Cocoon Swaddle Sack (Starbeam, UK page called Cocoon Swaddle Bag): A blog describes it as an award-winning no-origami swaddle that is easy to use but hard to escape from, aimed at warm weather and rated for 24°C-plus days and nights, with organic cotton and, it says, no synthetic material, and patented arm-hole poppers that let it be used up to 12 months. The sources disagree on the fabric: another source in this pack, the GoodtoKnow review, instead lists 5% elastane. Several users report the swaddle creeping up over the baby's face when the arms are in, and describe this as a suffocation risk even in what they believe is the correct size.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.

- /agent/tools.json is every tool, its arguments and its answers.
- /agent/merchants is every store you can buy from through RoboTrunk.
