Astronaut and Dinosaur Baby Sleep Sack


Our design has been based on the traditional technique of swaddling, which is when a newborn is cocooned or wrapped snugly in a blanket to imitate the secure and supportive feeling of being in the womb. Swaddling can now be achieved by using a baby sleep sack which will comfort, cool, and relax your little one as they drift off to sleep.


  • Innovative Breathable Organic Cotton: Our lightweight and breathable organic cotton baby sleep sacks help to regulate your baby’s skin, keeping them cool during the summer and cozy throughout the winter. A blend of 95% organic cotton and 5% elastane, they are quick-drying to minimize nighttime sweating, which helps promote a higher quality of sleep.
  • Zero Toxins & Free From Harmful Substances - We work hard to provide baby sacks that exceed safety standards set by CPSC, FDA and CPSIA and are safe on sensitive skin. Every thread, zipper and accessory on our baby sleep sacks are rigorously tested to ensure they’re free from toxins, harmful chemicals and phthalates.
  • Temperature Regulating - 0.5 TOG value. Perfect for year-round use. Toxin and phthalates free. Suitable for babies sized 17-24". 

Since sleep is a key part of early childhood development, helping your bundle of joy to sleep peacefully at night will not only give you more beauty sleep but also allow your baby’s imagination to run wild as they dream and develop their skills through memory and cognitive development. At LullaBear, we offer lightweight, breathable organic cotton baby sacks with playful and bright designs. Temperature regulating and easy to wrap your little one in, they also make wonderful baby shower gifts for new parents.

      Swaddling not only cocoons a baby and makes them feel safe, but it also helps reduce scratching as they sleep. Our baby sleep sacks are sleeveless and tucks in their little arms and legs neatly as they dream. 


      We know how tricky it can be to dress a newborn baby, so our baby sleep sacks have been made to be slipped on around the shoulders and adjusted using a Velcro attachment and small ties at the bottom of the baby sack.


      We made it easier to quickly change your baby’s diaper without removing the entire sleep sack via a quick-access zipper down the side. Perfect for when you’re on the go.
