When fitting your sling or carrier on yourself, make sure you hold your baby with at least one arm at all times until they are firmly positioned in the sling or carrier.
Make sure your baby's hips are in an ‘M’ position, so their thighs are straddling your body. Carrying your baby with their hips together can increase their risk of hip dysplasia which is a problem that can cause your baby’s hip joint to be unstable.
Position your baby in an upright position with the natural curve of their spine and the back of their neck supported.
Do not place your baby on your back in a carrier or sling until they can get into and maintain a sitting position on their own. Most baby carriers are not supportive enough to safely carry your baby on your back earlier than this.
