Stretchy Wraps plain or patterned and baby carriers patterned.
The T.I.C.K.S Rule for Safe Babywearing. Keep your baby close and keep your baby safe. When you're wearing a sling or carrier, don't forget the T.I.C.K.S.
TIGHT Slings and carriers 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 on 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. The fabric of a sling or carrier should not close around them so you have to open it to check on them. In a cradle position your baby should face upwards not be turned in towards your body.
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 a baby should never be curled so their chin is forced into their chest as this can restrict their breathing. Ensure there is a always space of at least a finger width under your baby's chin.
SUPPPORTED BACK in an upright carry a baby should be held comfortably close to the wearer so their back is supported in its natural position and their tummy and chest are against you. If a sling is too loose they can slump which can partially close thier airway. (this can be tested by placing a hand on your baby's back and presssing gently - they should not uncurl or move closer to you.) A baby in a cradle carry in a pouch or ring sling should be positioned carefully with their bottom in the deepest part so the sling does not fold them in half pressing thier chin to their chest.
