Size: Medium Color: Sanddaisy Number of Items: 1
Let me just say, this Lulumoon Sleep Sack Muslin for Baby has been a total game-changer for bedtime in our house! It’s the perfect mix of comfort, functionality, and style, and my baby (and I) absolutely love it. What Makes It So great stunning design, This sleep sack is absolutely gorgeous! The color is soft and elegant, and the inside lining has the prettiest little print that makes it feel extra special. It’s one of those products that looks like it belongs in a high-end boutique. Super Soft and Lightweight: The muslin cotton is incredibly soft to the touch it feels like it was made with a baby’s delicate skin in mind. It’s lightweight yet cozy, perfect for keeping my baby comfy in warmer months or layering in cooler weather. It’s breathable and just feels so luxurious! Incredibly Functional: The zipper is a lifesaver! It zips from the bottom, which makes nighttime diaper changes ridiculously easy no fuss, no stress. Plus, it’s roomy enough for my baby to wiggle and stretch while still staying safe and snug. The Lulumoon Sleep Sack Muslin for Baby isn’t just a sleep sack it’s a little piece of baby luxury. It’s soft, functional, and absolutely beautiful, making bedtime feel like a dream for both baby and mom. If you’re looking for something that checks all the boxes and adds a touch of elegance to your baby’s routine, this is the one to get. I can’t recommend it enoug ... show more

Nice sleepsack. Definitely more on the warmer side. Easy to put on and take off. Washes well and stays soft. Highly recommend for great organic cotton option.

  • Bit short for the size
Size: Large Color: Greentwig Number of Items: 1
Seems a bit short for the size. My babies are long so I always size up, sometimes 2 sizes, but even sizing up this is very short and I won't be able to use it as long as other brands. I like the quality and softness. Easy to care for and nice cotton fabric and the breathability for summer. Its not to heavy and nice weight. Great for sleeping in spring summer or fall. ... show more

  • Awesome sleep sack
Size: Small Color: Sanddaisy Number of Items: 1
Love this sleep sack. It's so easy to put on and take off. Zipper goes both ways and the shoulder straps are snaps so you can put a sleeping baby in the sleep sack with minimal disruption. The sleep sack itself is cute and the material nice and breathable

  • We love it!
Size: Medium Color: Greentwig Number of Items: 1
We use it every night for our little man. It’s so soft, warm & super cute! The butting snaps on the shoulders is so nice & convenient especially if you’re putting baby to bed & they’re already asleep! The size is perfect for 6+ months & our little man loves it. He doesn’t like to feel constricted when he sleeps & he can wiggle all around while sleeping & still be warm and covered! He sleeps so much better with this rather than a swaddle. ... show more
