Baby's bum should always be on the seam. Once your baby is snug within your sling, adjust the sling by folding the fabric down over your shoulder. Make sure the fabric is flat against your back to fully distribute baby's weight and prevent back pain.
How to determine your size:
Measure from your shoulder to the opposite hipbone with a soft tape measure. Your baby sling measurement will usually correspond to your t-shirt size. Correct sizing is important. The weight limit for our slings is 35 lbs. Please feel free to contact us if you are having a difficult time determining your size. We would be happy to help.
