  • Best swaddle/sleep sack!
Color: Teal Planets Size: Medium
We tried many different brands including the Halo and this one is the best. It’s snug enough, good quality material, and my son sleeps so well with it. He has slept 8-9 hours every night since 6 weeks old.

  • So cute
This is so cute and just like the one that comes in your happiest baby box with your snoo. It fits perfectly on our tall baby and she is so comfortable with the option to keep her arms out to have access to her hands.

It's a lifesaver for all the eczema babies and their tired parents. Quality sleep? Check. Reduced itching? Double check. If you're in the eczema battle, trust me, this sleep sack is your secret weapon. 🌙👶🔥 ... show more

  • Strawberry Snoo Swaddle
I love that the color of the swaddle is cream and matches the bedding that comes with the Snoo perfectly. I do wish the swaddle was able to be dried in the dryer at high heat. When I take the swaddle out the inside parts that Velcro are still damp and it takes some time to be fully dried. When it comes to having babes, you always need more than one or two swaddles because of blowouts and spit ups. ... show more
