Three-year-old children always eat their hands may be caused by bad habits, psychological factors, xenophagy and other reasons.
1. Bad habits: usually because three-year-olds are curious and like to put their hands in their mouths, they develop bad habits.
2. Psychological factors: 3-year-old children always eat their hands due to insecurity and lack of parental companionship, and usually need psychological counseling to improve the symptoms.
3. Ectophagia: diseases such as iron deficiency, zinc deficiency and parasitic diseases may lead to ectophagia. When a three-year-old child eats his hands all the time, it is usually accompanied by symptoms such as malnutrition, picky eating and loss of appetite.
There may be many other reasons why a three-year-old child keeps eating his hands. Parents are advised to take their children to the doctor to clarify the cause of the disease and to have regular treatment.
