Infants and toddlers can have mental health and developmental disorders that affect development. These include disorders that are specific to that stage of development (e.g., Excessive Crying Disorder) as well as general disorders that manifest themselves in particular ways in the infant-toddler population (e.g., Social Phobia and Autism Spectrum Disorder). However, these disorders—if properly identified using diagnostic criteria relevant to infant and early childhood development and experiences—can be effectively treated.
