Gentle on baby's skin

The ultra-soft cotton is perfect for my baby's sensitive skin. She seems very comfortable in it all night.

Not the right fit for us

Gina K. · 2026-05-11 · Verified purchase

This sleep sack didn't work for my baby; the sizing felt off even though we got the Small. It seemed restrictive around the legs, making it uncomfortable for her to kick around. The fabric, while cotton, felt a bit thinner than other brands we've tried. We ended up switching to something different because she just wasn't settling in it.

Helped with swaddle transition

Elise L. · 2026-06-24 · Verified purchase

We were struggling to move our little one out of her swaddle, and this sleep sack has been a huge help. She still feels secure and warm, but has more freedom to move her arms. The fabric is wonderfully soft and washes really well without losing its feel. We use the Hugs Kisses one and it’s adorable.
