  "question": "Which sleep sacks offer good value for money over a child's early years?",
  "answer": "ergoPouch Sleep Suit Sack (Sleep Suit Bag): The Bon Appetit 1.0 TOG Sleep Suit Sack is listed in three sizes: 3-12M, 8-24M and 2-4Y. This review rated build quality highly, describing soft, substantial organic cotton, flat-locked seams, YKK zippers with fabric guards and stainless-steel snaps. The writer found that converting the bag into a suit with legs stops the sleeping bag coming off when a baby pulls up to stand, and makes car-to-cot transfers simple.\nergoPouch Sleep Suit Sack 1.0 TOG Daydream: The Daydream 1.0 TOG colourway is listed in three sizes: 3-12M, 8-24M and 2-4Y. The organic cotton is described as soft, substantial and well finished, with flat-locked seams, guarded zippers and stainless steel snaps. The bag-to-suit conversion stops the sleeping bag coming undone when a baby pulls up to standing or walks.\nergoPouch Sleep Suit Sack 3.5 TOG: The Fruit Salad print is listed in three size runs: 3-12M, 8-24M and 2-4Y. The maker says it comes in five sizes, and recommends the sack configuration for 3-12 months and converting to the suit around 12-15 months when walking begins. The store's own product page shows an average customer rating of 4.9 out of 5 stars from 2,128 reviews.\nergoPouch Sleep Sack 2.5 TOG Willow: ergoPouch lists it as a Sleep Sack in the Willow print at 2.5 TOG, sold in 2-4Y, 3-12M and 8-24M. The US listing shows an average rating of 4.9 out of 5 from 1,098 reviews.\nergoPouch Cocoon Swaddle Sack 1.0 TOG Starbeam: Structured product data on the store page lists the available sizes as 3-6M and 6-12M. After twelve weeks of daily use and frequent washing across four newborns the fabric showed minimal pilling and kept its shape.\nergoPouch Cocoon Swaddle Sack: The Starbeam 0.2 TOG Cocoon is sold in three sizes: 0-3M, 3-6M and 6-12M. A test of four newborns over twelve weeks found the organic cotton noticeably premium, the snaps secure, the two-way zip allowing nappy changes without full removal, and minimal pilling after frequent washing.",
