Why toddlers eat sand — and when parents should worry
A pediatrician explains that toddlers putting sand or other inedible items in their mouth is usually a normal developmental phase, but persistent behavior after age two may signal an underlying health issue. Parents are advised to supervise children and consult a doctor if the habit continues.
When a toddler suddenly scoops a handful of sand into their mouth at the playground, parents often panic. Zane Līkopa, a pediatrician at the Children's Clinical University Hospital, explains that this behavior is typically a normal part of early development rather than a sign of a hidden problem.
Exploring the world by mouth
Young children explore their surroundings using all their senses — touching, listening and, frequently, putting objects in their mouths. This applies not only to toys but also to pebbles, leaves and sand. The habit is most common up to around 18-24 months and gradually fades as children grow, so a single instance of a toddler tasting sand is not cause for alarm.
When to seek medical advice
The situation differs if a child regularly tries to eat non-food substances such as sand, dirt, chalk or paper, and this continues past age two or becomes especially pronounced. This persistent pattern is medically known as pica, and possible underlying causes include iron deficiency or developmental conditions, including autism spectrum disorders. The pediatrician stresses that if such behavior is repeated and long-lasting, parents should consult a family doctor or pediatrician to rule out health concerns.
Is sand dangerous?
Swallowing a small amount of sand by accident usually does not cause serious harm, but sand is not sterile and may contain microorganisms or even sharp objects. If a child develops severe stomach pain, repeated vomiting, diarrhea or fever after swallowing sand, medical attention is needed.
Making the sandbox safer
To reduce risks, experts recommend covering a sandbox when not in use, regularly checking and replacing the sand, supervising children while they play, and washing hands afterward. At the same time, the pediatrician notes that excessive sterility is not desirable either, since exposure to microbes contributes to a healthy immune system.
