Write Your Number on Their Wrist Before You Enter
A temporary tattoo pen or a simple waterproof marker. Write your mobile number on your child's inner wrist before the family steps into any pandal crowd. Do this even if your child is old enough to memorise the number, noise, panic, and crowd pressure erase memorised information fast. A wristband with a luggage tag looped through it works just as well. The number on the wrist is the fastest thing a stranger, a police volunteer, or a festival organiser can use. Lanyard-style ID cards sold at stationery shops near major Ganesh festival grounds cost under twenty rupees and clip to a shirt collar. Buy ten at the start of the season.
