An infant or baby is the very young offspring of human beings. Infant is a formal or specialised synonym for the common term baby. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In medical contexts, a newborn or neonate is an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants.
Elimination communication (EC) is a practice in which a caregiver uses timing, signals, cues, and intuition to address an infant's need to eliminate waste. Caregivers try to recognize and respond to babies' bodily needs and enable them to urinate and defecate in an appropriate place. Caregivers may use diapers (nappies) as a back-up in case of "misses" some or all of the time, or not at all. EC emphasizes communication between the caregiver and child, helping them both become more attuned to the child's innate rhythms and control of urination and defecation. The term "elimination communication" was inspired by traditional practices of diaperless baby care in less industrialized countries and hunter-gatherer cultures. Some practitioners of EC begin soon after birth, the optimum window being zero to four months in terms of helping the baby get in tune with their elimination needs, although it can be started with babies of any age. The practice can be done full-time, part-time, or just occasionally.
The laryngeal theory is a theory in historical linguistics positing that Proto-Indo-European had a number of laryngeal consonants that are not reconstructable by direct application of the comparative method to the Indo-European family. The 'missing' sounds remain consonants of an indeterminate place of articulation towards the back of the mouth, though further information is difficult to derive. Proponents aim to use the theory to:
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements. The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
Baby sign language is the use of manual signing allowing infants and toddlers to communicate emotions, desires, and objects prior to spoken language development. With guidance and encouragement, signing develops from a natural stage in infant development known as gesture. These gestures are taught in conjunction with speech to hearing children, and are not the same as a sign language. Some common benefits that have been found through the use of baby sign programs include an increased parent-child bond and communication, decreased frustration, and improved self-esteem for both the parent and child. Researchers have found that baby sign neither benefits nor harms the language development of infants. Promotional products and ease of information access have increased the attention that baby sign receives, making it pertinent that caregivers become educated before making the decision to use baby sign.
Babbling is a stage in child development and a state in language acquisition during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words. Babbling begins shortly after birth and progresses through several stages as the infant's repertoire of sounds expands and vocalizations become more speech-like. Infants typically begin to produce recognizable words when they are around 12 months of age, though babbling may continue for some time afterward.
Thomas Berry Brazelton was an American pediatrician, author, and the developer of the Neonatal Behavioral Assessment Scale (NBAS). Brazelton hosted the cable television program What Every Baby Knows, and wrote a syndicated newspaper column. He wrote more than two hundred scholarly papers and twenty-four books.
Baby talk is a type of speech associated with an older person speaking to a child or infant. It is also called caretaker speech, infant-directed speech (IDS), child-directed speech (CDS), child-directed language (CDL), caregiver register, parentese, or motherese.
Burping is the release of gas from the upper digestive tract of animals through the mouth. It is usually audible.
Vocabulary development is a process by which people acquire words. Babbling shifts towards meaningful speech as infants grow and produce their first words around the age of one year. In early word learning, infants build their vocabulary slowly. By the age of 18 months, infants can typically produce about 50 words and begin to make word combinations.
Language development in humans is a process which starts early in life. Infants start without knowing a language, yet by 10 months, babies can distinguish speech sounds and engage in babbling. Some research has shown that the earliest learning begins in utero when the fetus starts to recognize the sounds and speech patterns of its mother's voice and differentiate them from other sounds after birth.
A scream is a loud/hard vocalization in which air is passed through the vocal cords with greater force than is used in regular or close-distance vocalisation. This can be performed by any creature possessing lungs, including humans.
Child development stages are the theoretical milestones of child development, some of which are asserted in nativist theories. This article discusses the most widely accepted developmental stages in children. There exists a wide variation in terms of what is considered "normal", caused by variations in genetic, cognitive, physical, family, cultural, nutritional, educational, and environmental factors. Many children reach some or most of these milestones at different times from the norm.
Phonological development refers to how children learn to organize sounds into meaning or language (phonology) during their stages of growth.
Crying is the dropping of tears in response to an emotional state or pain. Emotions that can lead to crying include sadness, anger, excitement, and even happiness. The act of crying has been defined as "a complex secretomotor phenomenon characterized by the shedding of tears from the lacrimal apparatus, without any irritation of the ocular structures", instead, giving a relief which protects from conjunctivitis. A related medical term is lacrimation, which also refers to non-emotional shedding of tears. Various forms of crying are known as sobbing, weeping, wailing, whimpering, bawling, and blubbering.
Harvey Neil Karp, FAAP is an American pediatrician, author, and child development specialist. He is best known for his book "The Happiest Baby on the Block" and its accompanying DVD, that use his "5 S's" approach to infant care. He is also the creator of the Snoo, a smart bassinet.
Infant Potty Training: A Gentle and Primeval Method Adapted to Modern Living is a book about toilet training by Laurie Boucke. It is an expansion of ideas that were originally presented in a small self-published volume called Trickle Treat in 1991. Infant Potty Training was first published in 2000, is now in its third edition (2008), and has editions in German, Dutch, Italian and Japanese. Infant potty training is traditionally used in at least 80 countries.
Human ethology is the study of human behavior. Ethology as a discipline is generally thought of as a sub-category of biology, though psychological theories have been developed based on ethological ideas. The bridging between biological sciences and social sciences creates an understanding of human ethology. The International Society for Human Ethology is dedicated to advancing the study and understanding of human ethology.
Speech acquisition focuses on the development of vocal, acoustic and oral language by a child. This includes motor planning and execution, pronunciation, phonological and articulation patterns.
Infant crying is the crying of infants as a response to an internal or external stimulus. Infants cry as a form of basic instinctive communication. Essentially, newborns are transitioning from life in the womb to the external environment. Up to 27% of parents describe problems with infant crying in the first four months. Up to 38% identify a problem with their infant crying within the first year. Parents can be concerned about the amount of time that their infant cries, how the infant can be consoled, and disrupted sleeping patterns. Colic is used as a synonym for excessive crying of infants, even though colic may not be the cause of excessive crying.
