Infants cry as a form of basic instinctive communication.
A crying infant may be trying to express a variety of feelings including hunger, discomfort, overstimulation, boredom or loneliness. Many caregivers employ the use of baby monitors or babycams which enable them to hear or see an infant's cries from another room.Feeding is typically done by breastfeeding, which is the recommended method of feeding by all major infant health organizations including the American Academy of Pediatrics. However, if breastfeeding is not possible or desired, bottle feeding may be done with expressed breast-milk or with infant formula.
Infants have a sucking instinct allowing them to extract the milk from the nipples of the breasts or the nipple of the baby bottle, as well as an instinctive behavior known as rooting with which they seek out the nipple. Sometimes a wet nurse is hired to feed the infant, although this is rare, especially in developed countries.As infants age, and their appetites grow, many parents choose from a variety of commercial, ready-made baby foods to supplement breast milk or formula for the child, while others adapt their usual meals for the dietary needs of their child.
Infants are incontinent, therefore diapers are generally used in industrialized countries, while methods similar to elimination communicationare common in third world countries.[citation needed] Practitioners of these techniques assert that babies can control their bodily functions at the age of six months and that they are aware when they are urinating at an even earlier age. Babies can learn to signal to the parents when it is time to urinate or defecate by turning or making noises. Parents have to pay attention to the baby's actions so they can learn the signals.Children need a relatively larger amount of sleep to function correctly (up to 18 hours for newborn babies, with a declining rate as the child ages), specially after feeding.
