It’s actually to commemorate the little one turning 100 days old-the end of baby’s supposed fourth trimester and to celebrate the baby’s first official solid food consumption.
It’s also named as anti-drooling ceremony! It has been passed on from generations and is very popular in country like China and Taiwan..
The baby biscuits are to be tied with a string, hang around the baby’s neck. This is to prevent excessive drooling in a baby. After the solid food, a baby’s hair will be lightly trimmed!
