Soothe and calm

Settle baby with arms in to help them feel nice and secure just like when they were in mommy's tummy. As they grow leave arms out for more freedom of movement.

Hip-healthy design

A unique curved seam gives the skirt area lots of room for baby to wriggle and allows them to lie in a natural 'froggy-legged' position to help aid hip healthy development.

Prevents startling

With arms in and lined chest for secure swaddle comfort the Grosnug will help prevent the 'moro' or startle reflex and help baby settle more easily.

The sweet Wild Posy Grosnug is the only bedding you will need for your newborn. The Grosnug enables you to swaddle arms in or out for a great night's sleep.

Extremely easy to use with no folding needed, and a long zipper that opens from the bottom for diaper changes. Unique design creates space for hip-healthy, natural 'froggy-legged' position.

The Grosnug keeps your baby comfortable, and perfectly transitions them in to their first Grobag Sleep Bag. Supersoft and stretchy 100% cotton.

This Grosnug is available in cozy weigh for room temperatures between 57-68⁰F

My baby loves her grobag and does not sleep without it!

Firstly, the colors and softness are great! I love the versatility sometimes my babe likes her arms in, sometimes out. This is great for both and diapers changes! Definitely get this!

Love this! Super versatile for swaddling!! There are so many different options to make sure your baby is always comfortable. First it unzips all the way to make it super easy to get your baby in and out. Also the bottom unzips when it is time for diaper changes. You can swaddle with arms in, 1 arm out or both arms out. The bottom is also roomy enough so they can move their feet. The zipper is super convenient since you don't have to fuss around with wrapping anymore. Definitely will help your baby to sleep longer and be more comfortable

My daughter is a picky swaddler. She likes to be swaddled, but also likes having her hands. This swaddle was perfect. It’s easy to use, just zip it around, and you can give access to one or both arms by simply unsnapping the arm holes. The zipper ends at the bottom, so nighttime diaper changes are easy and you don’t have to fully unswaddle. The fabric is slightly water resistant so you can easily wipe up spit ups or spilt milk and not worry about having to change the swaddle because it’s wet. The color was also super cute and I appreciated the different styles and fabric weights available. This has become my go to swaddle for bedtime.

I got the grosnug swaddle sleeping bag just a few weeks ago. The fabric is super soft and strechy. It is also light weight. The print is also super cute! It washed just fine, it didn't fray, winkle or shrink up. I love the arms in or out feature this swaddle sleeper has! My little one likes her arms in while sleeping but out while nursing. So in the middle of the night I just had to undo the buttons to let her arms out. Super simple! The zipper goes from top to bottom and is concelaed at each end. I got the light version, if I had known there was a cosy (warm) option I would've wanted that for winter. But this would be a great spring/summer swaddle sleeper or if your house is above 70 in the winter. This also came with a nursery thermometer, which was an added bonus.

Love this swaddle bag. I enjoy having the zipper on the bottom it makes diaper changes so smooth. Having the snap buttons to keep the arms in make it so that my baby who likes to wiggle stays in it snuggly and safely!
