Poor feeding is when an infant has a lack of interest in feeding or a problem receiving the proper amount of nutrition.

Poor feeding is a nonspecific symptom seen in newborn and young infants that can result from many conditions, including infection, metabolic disorders, genetic disorders, structural abnormalities, and neurological disorders.

Poor feeding is not an indicator of the severity of the disease, but it is an indicator that (even in the absence of other symptoms) suggests close watching of the infant. Poor feeding is not the same as "picky" eating. Many children between ages 2 and 4 are picky eaters. Parents only need to give children what they like to eat at this age. However, children must continue to drink milk or an appropriate milk substitute.
