The T.I.C.K.S. Rule
The English abbreviation T.I.C.K.S. indicates 5 rules for carrying a baby that will ensure a comfortable wearing experience for the mother, and meet the baby's healthy developmental requirements.
T is for Tight: Your wrap should be tight, with your baby held close against your body. Loose fabric or buckles can allow your baby to slump, which can make it difficult for it to breathe. A loose wrap can also strain your back.
I is for In View At All Times: You should always be able to see your baby’s face by simply glancing down. The fabric of a wrap should not close around them so you have to open it to check on them. In a cradle position your baby should face upwards and not be turned in towards your body.
C is for Close Enough To Kiss: Your baby should be positioned as high on your chest as you find comfortable. If you tip your head forward, you should be able to kiss its forehead or the top of its head.
K is for Keep Chin Off The Chest: Your baby should not be in a position where its chin is forced onto its chest as this can restrict breathing. Make sure you can put at least one finger between chin and chest to keep it safe.
S is for Supported Back: Your baby's back should be supported in its natural position so it isn't bent or twisted. Place a hand on the back and gently press. It should not uncurl or move closer to you. For a healthy hip position, make sure that the pouch or base of your carrier is wide, with your baby's legs supported to the knees. This will create an M shape, where its bottom is the middle trough and its knees rest above its hips as the peaks. This position is particularly important if you have a newborn, or if your baby has hip dysplasia or other hip problems. In these cases, your baby's legs should never hang straight down.
