La Petite Chose Organic Baby Sleep Sacks

Replacing blankets in a crib, a sleep sack is recommended by pediatricians as the safe way to put your baby to bed. Babies, like adults, sleep better when they're cozy in a cooler room. Our sleep sacks are like the difference between sleeping under a sheet or a fleece blanket and sleeping under a soft duvet. Our sleep sacks are:

  • Safe, certified free of chemicals you don't want next to your baby's skin.
  • Sustainable, ethically made with OEKO-TEX certified organic cotton. 
  • Adjustable, they grow with your baby and last longer. 
  • Easy, opening flat with a 2 way YKK zipper and strong shoulder snaps.
  • Cozy, quilted for comforting softness and warmth. 
  • Unisex, a beautiful part of your baby's nursery.

"My daughter adores it, in fact, it has improved our bedtime routine. Every night since she’s worn it she’s fallen asleep independently without a peep. It is so beautifully made, thick and luxurious, but also doesn’t make her sweaty in the night."
