You usually need to tie the shawl about 3 times before you really understand how it works. Try tying it first with a doll or teddy bear to get the technique down before you put it on your child. If possible, try the first time with your child when they are full, satisfied and have a freshly changed nappy. Then, once both you and your baby are comfortable in the sling, putting your baby in the sling is usually one of the best ways to calm a sad and anxious baby.
After putting your baby in the sling for the first time, walk around for a while until the baby has settled down. If your baby starts to whine when put in the sling with mum, but becomes quiet when put in the sling with dad, this indicates that the baby is hungry and is being teased by the smell of milk from mum. In this case, mum can try using a dummy or, better still, breastfeed the baby in the sling. Or dad can carry the baby for a while instead!
If you have trouble getting the knots right after trying several times, contact your dealer and ask for help.
