Before you beat your child for stealing, read this;
Several times it happens that a child spreads its hand to take something that is not his. He forcibly tries to take the eatables, fruits or toys of some other child. Stealthily takes away something from the pocket of the father or from the mother’s purse. He takes sweets and other goodies from the pantry without the knowledge of his mother.
Picks up things stealthily from the shops visited by the family. Takes pencils, rubber etc of his siblings and school-mates without informing them. Several children do this sort of things in their childhood.
