Chewing on toys, necklaces, or any small-ish item within reach is normal behavior for a one-year-old. Baby might even try to put a leaf or a rock in her mouth if it looks particularly interesting. A few germs from items like these won’t harm her, and you’ll usually be able to steer her toward something edible pretty easily. However, if your child continues to try to eat non-food items and can’t be convinced to stop, it could be a sign of pica.
Pica is an eating disorder diagnosed when a person shows a pattern of eating non-food materials like dirt or paper for more than a month. It’s more likely to affect children than adults, but it can also affect pregnant women. According to the National Institutes of Health, up to a third of children ages 1 to 6 are affected by eating behaviors associated with pica.
Pica is common among people with developmental disabilities or brain injuries, and it can also be triggered by lack of nutrients or no specific reason at all. A child could like a certain texture, taste, or maybe even the attention she receives when she eats something strange. People with pica are drawn toward eating things like dirt, paper, clay, chalk, hair, paint, ice, sand, soap, or feces.
When a child eats something she isn&;t supposed to as a result of pica, it can cause pain, nausea, vomiting, bloating, fatigue, or other symptoms. If the substance is dangerous, she can get an infection or accidentally poison themselves. If your child often tries to eat non-food items, it’s important to take her to a healthcare provider for evaluation and treatment.
There isn’t a specific test for pica, but your healthcare provider will be able to evaluate your child to make sure there haven’t been any negative health effects from her eating patterns and refer you to a specialist who can work with you to help establish normal eating patterns.
Sometimes pica will truly only be a phase that lasts a month or so, and sometimes it will go on for several months before disappearing. There are some cases in which it lasts into adulthood, but continued therapy can help reduce the negative side effects. In most cases, toddlers who put non-food items in their mouths are just exploring, but occasionally, toddlers who regularly engage in these behaviors, especially with a specific substance, can benefit from talking through the issue with a healthcare provider.
