Choosing a Swaddelini Swaddle Size by Baby's Weight
How should I choose the swaddle size that matches my baby's weight?
Swaddelini The Gift Swaddle Sleep Sack: Two arms-in sizes: Small for babies 6-12 lb and Large for 12-18 lb; a baby born over 9 lb should still take the Small, because the Large will be too big. Arms must be left out once a baby starts showing signs of rolling over. Swaddelini Swaddle Sleep Sack: Two sizes: Small fits 6-12 lb and Large fits 12-18 lb; a baby born over 9 lb should still take the small because the large will be too big. Both sizes can be used as a transition swaddle. A buyer of an 11 lb, 10-week-old said she would not recommend it for babies over 10 lb: her baby kept pulling her hands up toward her head, could not get them to her mouth and became frustrated. Swaddelini BS Swaddle (Small) and BL Swaddle (Large): The Blue Swaddle Sleep Sack comes in two arms-in sizes: Small for 6-12 pounds and Large for 12-18 pounds. 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.
