This is the ONLY sleep sack my baby will sleep in! What makes it extra special to me, is the custom embroidery. There’s no fabric fraying after multiple washes. He loves his arms free and hates to be swaddled, so I knew this sleep sack would be a great fit for him. We went from waking up every 1-2 hours to now every 3-5. Keeps my mind at peace knowing my baby is not only comfortable, but also safe in this!
