Sleep sacks with a neck opening that suits a newborn
Which sleep sacks have a neck opening that fits a newborn well?
ergoPouch Cocoon Swaddle Sack: The swaddle is deliberately firm around the neck, shoulders and chest so the baby cannot slip down inside it. ergoPouch says the correct fit is when two fingers can be placed inside the neck opening. Love To Dream Swaddle Up™ Original 1.0 TOG: There is a zip guard at the top of the neckline to protect the chin and skin, and the neck hole should be checked for fit. Parents ask whether the snug neckline is a concern; one advises that if you cannot slip fingers between the neck and the suit it is probably too tight, and another says it never bothered her baby.

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. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
