I really think my baby started sleeping better as soon as he started wearing this. It’s so soft and cozy. I want one for myself! I got one for his daycare use and all of his care providers were enamored with it. Everyone that sees it and feels it wants one. I’m really grateful to have a non toxic sleep sack option for my baby. They spend so many hours sleeping it feels incredibly important. I highly recommend this product. I should also mention that I have now washed it once and I was worried it would loose it’s luxurious softness or change in size but it did not. Seems really solidly made.
