How To Swaddle Your Baby
Spread the swaddle into a diamond shape. Then fold the top corner down about two thirds of the way to the bottom corner, to form a triangle. Lay your baby in the middle of the triangle, with his or her shoulders slightly below the fold, and his or her head above the fold.
Leaving your baby’s right arm slightly bent at the elbow, place it flat against his or her body. Then bring the left corner of the swaddle across your baby’s tummy, and tuck it securely under his or her body. Make sure the right arm is now secured under the fabric, and the swaddle is tight (important).
Bring the bottom corner of the swaddle up and over your baby’s legs. Hold firmly to keep swaddle tight.
Leaving your baby’s left arm slightly bent at the elbow, place it flat against his or her body. Then bring the right corner of the swaddle across your baby’s tummy, tucking any remaining material underneath your baby to anchor the swaddle.
