A mother’s review: “I highly recommend using a Safe T Sleep combined with a baby sleeping bag – it’s the perfect combination for babies once they are no longer swaddled. It means your baby is warm and won’t wake up cold, or under the covers, plus it’s great to have the peace of mind that your baby is in a safe sleeping position all night. We always recommend the Safe T Sleep & sleeping bag combination for parents looking to teach their babies to sleep settle, and learn to sleep through the night”.

“Love the Safe T Sleep! From an early age my daughter, in her gogo bag, would wriggle to the top of her bassinet, get her face stuck in the padded sides, and wake screaming. We rushed out and bought a safe t sleep and all slept better as we no longer had to worry about her. She used this until she could sit up in her cot. It was also useful when we went away as we used the extension to secure her to a single bed when we needed to.”
Many parents, grandparents and caregivers are using the combination of a baby sleeping bag with the Safe T Sleep Sleepwrap baby swaddle in order to keep babies from newborn to 2years old even safer and cosier while sleeping. https://www.safetsleep.com/collections/all-safe-t-sleep-products
