How does it differ from a sleeping bag? And, most importantly, how do you choose the right one to ensure a safe and comfortable night\u2019s sleep? This guide explains it all. \ud83c\udf19<\/p>\n<h2>\ud83d\udd0d Sleep sack baby: definition and origin of the word<\/h2>\n<p>\u00abSleep sack\u00bb is a registered trademark created in the 1960s by a French company; it has since become a common term used by millions of French-speaking parents. Just as \u00abFrigidaire\u00bb refers to a fridge or \u00abScotch\u00bb to adhesive tape, \u00absleep sack\u00bb is synonymous with sleeping bag or a baby sleeping bag.<\/p>\n<p>A sleep sack baby is therefore a <strong>wearable sleeping bag<\/strong> baby slips their legs and body into it, with their arms free, and the fastening (usually a zip) keeps the garment in place during the night. Unlike a blanket, it cannot ride up over baby's face.<\/p>\n<h2>\u2705 Why use a sleep sack rather than a blanket?<\/h2>\n<p>The French Paediatric Society and the French National Health Authority recommend the sleep sack (sleeping bag) as a safe sleeping arrangement for infants. The reasons are:<\/p>\n<ul>\n<li><strong>Security<\/strong> cannot cover baby's face during the night, unlike a blanket<\/li>\n<li><strong>Stable thermal comfort<\/strong> baby's temperature stays stable even if they roll over or fidget<\/li>\n<li><strong>Freedom of movement<\/strong> legs move freely in the sack \u2014 essential for hip development<\/li>\n<li><strong>Practicality<\/strong> night-time changes are made easier with a two-way zip (you open from the bottom without completely undressing baby)<\/li>\n<\/ul>\n<h2>\ud83c\udf21\ufe0f Choosing the TOG rating for your sleep sack<\/h2>\n<p>TOG is the warmth rating for the sleep sack.

In shops, you will find the same products sold under the names \u00absleeping bag\u00bb, \u00absleep sack\u00bb or \u2018baby sleeping bag\u2019. They all meet the same European safety standards.<\/p>\n<h3>From what age can a sleep sack be used?<\/h3>\n<p>From birth, with a 0\u20136-months style featuring armholes designed for infants. There are even special turbulettes for premature babies.<\/p>\n<h3>My baby is sweating in their sleep sack \u2014 what should I do?<\/h3>\n<p>Switch to a lower TOG rating or remove a layer of underclothing. A baby who sweats at night is too hot \u2014 the back of the neck should feel warm and dry, not hot and clammy.<\/p>\n<h2>\ud83d\udecd\ufe0f Turbulettes baby at PetitMaxou<\/h2>\n<p>Sleep sacks TOG 0.5, 1 and 2.5 in OEKO-TEX-certified organic cotton, with a two-way zip and chin guard: PetitMaxou offers the sleep sack range to suit every season.

Be wary of very low prices (&lt; 15 euros) on major online marketplaces \u2014 the quality of the filling and armholes may not be high enough to guarantee safety. A reasonable budget for a good sleep sack is 30 to 60 euros, depending on the TOG rating and the material. It\u2019s an investment that pays for itself quickly when you consider the 300\u2013400 nights it will be used for before moving up to the next size.<\/p>\n<h2>\ud83c\udf81 Sleep sack as a birth or baby shower present<\/h2>\n<p>The sleep sack is one of the most practical baby gifts and one that is least likely to be duplicated \u2014 unlike bodysuits and soft toys. Give a set comprising a sleep sack TOG 2.5 and a sleep sack TOG 0.5 to cover both seasons, or invest in a high-quality, adjustable design.
