Sleep sacks and keeping a baby's arms in

Will a sleep sack stop a baby from pulling their arms out?

ergoPouch Cocoon Swaddle Sack (also sold as ErgoCocoon Swaddle Bag): The single-zip design swaddles a baby securely with some arm freedom inside but no full escape, in arms-in, one-arm-out or both-arms-out options. 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 (also sold as ErgoCocoon and Cocoon Swaddle Bag): A parent reported that the 1.0 TOG version was far more spacious than the warmer TOGs, so it did not hold the baby's arms in like the snugger warmer bags. ergoPouch Cocoon Swaddle Sack 1.0 TOG Bon Appetit: Several owners report the 1.0 TOG version is much roomier than ergoPouch's other TOGs, so babies can work their arms out and it does not swaddle as snugly.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from. A dash means no checked fact fills that cell. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live.

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.
