  "question": "Which sleep sacks fit a newborn well around the neck and body?",
  "answer": "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. Size 0-3M (000) is 60 cm long, for babies 3-6 kg and about 62 cm tall. Caution: 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.\nergoPouch Cocoon Swaddle Sack 2.5 TOG: Parents in the discussions most praise the press-stud arm options, especially for babies who roll early, while the bag still feels firm across the chest. The size chart says to choose the size by the child's weight rather than age for safety. Several parents report the bag riding up over the baby's face while their arms are in, including during naps and overnight, which they describe as frightening.\nSwaddelini Black Swaddle Sleep Sack: The product page describes a seamless 3D-knit construction for cozy, secure wear. The small fits babies 6-12 lbs; if a baby is born over 9 lbs the maker still advises small because large will be too big; large fits 12-18 lbs comfortably.",
