Pester power refers to the urge that children have to nag and harass their parents or guardians to buy them things, especially toys and snacks. The term has been around for some time, but there are other terms that can describe the same behavior in children. One of these is "nudge marketing," where companies subtly encourage consumers to buy their products through gentle persuasion. Another term is "kidfluence," which refers to the influence children have over their parents' purchasing decisions. "Whine marketing" is also used to describe the persistent complaining and tantrums employed by children to get what they want. Regardless of the term used, it is important for parents to manage their children's demands and avoid giving in too easily.
