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. 
  • 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.

Our classic weight is  suitable for all year round except the hottest days of summer. It's designed to keep your baby warm in a cooler room. The lightweight is best for babies in consistently warmer climates or babies who simply 'sleep hotter'. Add or remove pajama layers under your sleep sack to adjust to your baby's room temperature. Here is a pajama chart for the classic weight.
