How to carry your baby safely in a wrap or baby carrier | User manuals and safety information

Tight. 
Your wrap should be tight enough to hug your baby close to you as this will be most comfortable for you both. Any slack/loose fabric will allow your baby to slump down in the carrier which can hinder their breathing and pull on your back.

In view at all times.
You should always be able to see your baby’s face by simply glancing down – make sure there is no fabric covering your child’s face.

Close enough to kiss
Your baby’s head should be as close to your chin as is comfortable. By tipping your head forward you should be able to kiss your baby on the head or forehead.

Keep chin off the chest.
Your baby should never be curled so their chin is forced onto their chest as this can restrict their breathing. Check you can get a finger under their chin (reach in from the side of the sling if you need to).

Supported back.
The wrap should support your baby’s back – and his tummy and chest should be against you. If you put your hand on your baby’s back and press gently s/he should not uncurl.
