According to healthcare professionals, many kids eat boogers because they are salty tasting. To keep your child from eating boogers, try using positive reinforcement when your child cleans their nose by using a tissue instead rather than reprimanding or scolding them for eating their boogers. Also, talk to them about the fact that boogers contain germs and that picking their nose spreads germs to other people. You also can try using a humidifier to keep their nasal passages moist and reduce the number of boogers they have. If you continue to have trouble getting your child to stop eating their boogers, talk to a healthcare provider for advice.
