Note that the shoulder straps are below baby's arm.

 

Try to ensure the baby's head is high up above the shoulder so that the baby can observe and learn what the parents are doing.

 

Ensure the shoulder strap are close to the body when tying off to prevent the baby from dropping lower subsequently. 

 

Do not bow forward 90 degree as it is possible for baby to fall from top.
