Swaddle size when a baby's weight is near a size boundary
Should a shopper buy a larger swaddle size than the baby's weight suggests?
Swaddelini Bamboo Pure Mint Swaddle Sleep Sack: The maker says the small fits babies 6–12 lbs, and even a 9 lb+ newborn should still get the small because the large will be too big; the large fits 12–18 lbs comfortably. Swaddelini Bamboo Blend Mint Swaddle Sleep Sack: On the maker's own page the sizing advice matches the FAQ: take the Small even if the baby is born over 9 lb, because the Large will be too big. Swaddelini Organic Cotton Swaddle Sleep Sack: For an unborn baby, the small size is recommended even if the baby is expected to be big. Swaddelini Blue Swaddle Sleep Sack: Forum replies warn that sizing can be off, so check the size guidelines carefully before buying.

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.
