Review on SwaddleMe Original Swaddle - Size Small, 0-3 Months, 2-Pack (Sleepy Forest): The Perfect Snug Wrap for Newborns by Jennifer Salazar

Make sure the Velcro on the chest is snug against the body. First put the sheet under your arm and then put your hands in the diaper. I've found that diaper thickness, room temperature, and mattress thickness all play a role in keeping the baby in a lying position. You'll have to play around with these three when changing any of the above inputs. Like higher temperatures, thinner diapers, thinner mattresses. hp This hole on the back is for changing the car seat.
