Symptom: Infant symptoms

Infant symptoms: Symptoms affecting babies and infants.
Introduction: Infants may exhibit a variety of symptoms due to medical conditions. Always seek prompt professional medical advice about any infant symptom. Professional advice about any symptoms is particular important for infants, because they are often unable to communicate exactly what is wrong.

Very common is a crying infant, which may be due to various simple reasons (e.g. hungry, thirsty, tired, lonely, etc.), or can indicate various medical conditions. For delayed or poor growth see growth symptoms and poor growth; loss of weight or delayed growth in an infant or child may be termed failure to thrive. Feeding problems may also indicate various conditions; see poor feeding. For other developmental delays (physical or mental), see developmental problems. Note that infants may also exhibit almost any symptoms, not just those mentioned, just as an adult can have any of numerous possible symptoms.
