To keep your garment looking and feeling its best, turn it inside out before washing. Use cold or warm water (below 30°C/86°F) and wash gently with like colors using mild detergent. Avoid harsh chemicals like bleach, which can weaken the fabric and fade the colors. For lasting softness, use short washing cycles and promptly remove from the dryer. While machine drying is fine, line drying helps your garment last longer. Always check the care label before ironing for specific instructions.

My 4 month old has had his longest sleep stretches the past two nights while wearing this sleep sack! I love the print and my baby loves his new sleep sack.
First time ordering from Larkspur, and I see many more orders for my daughter in the future! This sleep sack is the softest and warmest materiel, she sleeps so well in this! I highly recommend!!
I love this sleep sack! It is soft and high quality. Everything my baby needed it to be. ❤️
We don’t know how to live without this!
It’s so buttery soft I’m so jealous if you could make an adult one I’d live in it
Absolutely the best sleep sacks! We went from Kyte to these and it couldn’t have been a better decision! They fit better and wash soooo good!
Perfect fit and was very pretty
Product is beautiful but came wet
Love it!
I’d say these are pretty comparable to Kyte baby. They are super soft and have good weight to them. My baby sleeps amazing throughout the night and keeps her warm! We love the softness and quality!
our boy grows so fast that he can’t fit most sleep sacks, until larkspur!
