Why Do Toddlers Eat Dirt?

It is developmentally appropriate for young kids to put everything they come across in their mouths. They are exploring, are very curious and their sense of smell and taste leads them around. Usually, kids would defer from eating dirt again if they dislike the taste. However, sometimes it’s not just the taste, but also the texture that tempts kids to put things in mouth. After all kids know nothing about bacteria or viruses, they will do things just to please themselves. As kids grow up, this problem resolves on its own paired with your constant guidance. However, this habit becomes a concern when kids continue to eat dirt and other things during their primary school years. This disorder is called Pica or Geophagy and may be related to nutritional deficiency of calcium, iron or zinc in the body. Malnutrition is another condition which may induce craving for non-food items.
The kids develop irresistible urge to eat these inedible items. Pica is quite common in young kids up to the age of 6 and also in pregnant women. For kids, this may be an indicator of developmental disorders such as mental retardation or autism.


Kids tend to put various non food items in their mouths, owing to their curiosity and exploring nature. However, a kid with Pica would actually tend to have cravings for non food items, which other kids would outgrow with time and age. Between the ages of 1-6 years, 10% to 30% of kids are likely to develop this eating disorder.

The word pica has been derived from the Latin name of a magpie – which is widely known for its strange eating behavior. Pica has been found to be most common in children who have some kind of disability in development – autism, retardation,or even a brain injury. Not only kids, Pica can also be a problem for pregnant women and those with epilepsy.

Hazards of Eating Dirt For Children

Eating inedible stuff such as hair, sand or bird dropping may lead to gastrointestinal problems. There is an increased risk of such stuff blocking and harming the intestines. Nowadays, the soil is chemically contaminated, sprayed with insecticides and pesticides, loaded with bacteria even those from manure and sewage along with pet feces and worms. It may lead to various infections and even food poisoning. Continuous ingestion may lead to constipation, abdominal pain, vomiting, loss of appetite and diarrhea.


A condition which may lead to loss of vision, flare epilepsy or asthma, is caused by Toxacora worms found in the feces of dogs and cats which can easily find their way in soil.

Depending on the surroundings (proximity to factories), the soil may also contain heavy metals such as lead and arsenic. Lead is also found in paint and wood polishes commonly used in the household. Consuming large quantities of lead can damage the nervous system of young children. Arsenic, another harmful toxin can make kids more vulnerable to develop cancer. Eating dirt and sand may also lead to the deficiency of iron.

Benefits of Eating Dirt By Kids

With too much on your mind about harmful bacteria and viruses, well it’s just one side of the story. So how can eating dirt help? Read below:

  1. Develops immune system: Immune system releases antibodies to fight against external bacteria that are harmful for the body. Off late, a number of auto-immune disorders such as multiple sclerosis, inflammatory bowel syndrome as well as asthma and allergies have picked up their pace. In auto-immune disorder, the body makes antibodies and mistakenly destroys the healthy tissues or may not develop sufficient antibodies to fight infection. The hygiene hypothesis proposes that if immune system is trained, then it may be strengthened and thus increase resistance of the body. For this purpose, practicing in childhood by eating dirt is fine way to develop immunity
  2. Stress on Cleanliness: Another component of this theory holds that with exaggerated stakes on cleanliness, children are no more exposed to dirt and if suddenly countered by it, they are very prone to develop allergies. This is because their immune systems haven’t had any experience with fighting bacteria or viruses
  3. Mineral supplement: Clay or soil is rich in mineral components and may supplement diet in some cases
  4. Probiotic properties: Soil contains some bacteria which are healthy for your gut. So ingesting these may aid digestive functions. It has also been found to help in curing Crohn’s disease and leaky gut syndrome
  5. Heals stomach ache: Kaolin, a substance found in white clay has been used in medicines to heal stomach upsets. Caution: Anything of excess is bad, in this case, too much clay can get you constipated!

It’s interesting to know that some manufacturers used clay-like compounds to some vaccines to increase the immune system’s response. Also in ancient era, food was cooked in clay to protect from toxic alkaloids and tannic acid found in potatoes and bread. Who thought that eating dirt could actually have any benefits?

  1. Instead of just doing jhadu (sweeping floor), do wet mopping; preferably added with Savlon or Dettol
  2. Indulge in dusting – a solid reason to keep your house spic and span! This will prevent your little one from licking dust
  3. Make sure there are no chipped paints within the range of your kid
  4. Keep away pencil, eraser, paper, coins and such other small items from your kid
  5. Throw away pebbles, pet poop, stray leaves from your verandah and backyard. Eliminating the objects from the vicinity of the child to prevent him coming across them is a smart move!
  6. If you have potted plants, perch them high up on wall – away from your child’s reach
  7. If you have a garden, consider fencing it with a gate and make sure you are around your kid whilst he plays outside
  8. It’s best to supervise or play with your kids in the garden or if you have a separate sand play area. Infants can get choked by gritty sand. Also, you must advise them against throwing sand in others eyes, ear or mouth
  9. Keep pet food away from your child’s reach, it has been known to cause salmonella infections
  10. Also teach your kids to wash their hands and mouth after playing with the dirt

The usual dirt play may be safe, but supervision is necessary. Give a balanced diet to your child with an increased proportion of calcium, iron and zinc. These can be obtained from meat (esp. Red meat), liver, eggs, seafood, grains, cereals, and legumes and dairy products. Consult your pediatrician, who may prescribe supplements. In the end, it’s nothing to panic over, this is just a developmental phase and a reminder that your kid needs your attention and love!
