Infant crying is the crying of infants as a response to an internal or external

Misconceptions regarding the purpose of crying in the infant are common among caregivers and medical personnel. These are usually determined by cultural mores and not by evidence-based explanations. Infant crying is regarded by some to be normal.^[12][13] The belief that infants have a need to cry to expand or exercise their lungs is not supported by research. This is because a healthy newborn infant lung's are able to contain a sufficient amount of air plus a reserve.^[3] Birth trauma is related to the amount of crying. Mothers who had experienced obstetrical interventions or who were made to feel powerless during birth had babies who cried more than other babies.^[14] Babies who had experienced birth complications had longer crying spells at three months of age and awakened more frequently at night crying.^[15][16][17] When infants cry for no obvious reason after all other causes (such as hunger or pain) are ruled out, the crying may signify a beneficial stress-release mechanism, although not all sources agree with this. The "crying-in-arms" approach is a way to comfort these infants.^[18][19][20] Another way of comforting and calming the baby is to mimic the familiarity of the mother's womb.^[21] Consistency and promptness of maternal response is associated with a decline in frequency and duration of crying by the end of the first year, and individual differences in crying reflect the history of maternal responsiveness rather than constitutional differences in infant irritability.^[22]

Causes

Most infants cry in response to something, although it may be difficult to identify the cause. Sometimes there may be no apparent reason.^[23]

Some possible reasons include:^[24][23]

• Hunger
• Sleepiness (Normally just yawns or rubs eyes)
• Gas pain (for example, if the baby has not burped)
• Discomfort (for example, a wet diaper)
• Temperature (for example, feeling too hot or too cold)
• External stimulus (for example, too much noise or light)
• Boredom or loneliness
• Pain (for example, teething)

Excessive crying in infants may indicate colic or another health problem.^[24] Some health problems are listed below:

The term 'colic' was defined in 1954 as: "crying for more than three hours per day, for more than three days per week, and for more than three weeks in an infant that is well-fed and otherwise healthy."^[12] Colic and excessive crying by infants is synonymous to some clinicians.^[6] Colic is attributed to gastrointestinal discomfort like intestinal cramping.^[25] Clinicians often admit that colic cannot be treated or that alternative treatments are ineffective.^[26] The protocol followed by clinicians to treat colic is described as "treating the parents" with reassurance.^[12]

Maternal responses

Crying in infants is associated with high stress levels and depression in mothers.^{[27][28][1][4]} Excessive crying has also been linked to maternal "physical aggression" and "angry speaking." Mothers without assistance in caring for the infant, are more prone to physical aggression.^[1] During evaluations of maternal depression responses to infant crying, sleeping problems are closely associated with excessive crying. It is not always clear that when sleeping problems are associated with infant crying, whether the sleeping problems are descriptive of the mother or the infant or both.^[28] Maternal stress is associated with excessive crying.^[29]

Effects on young children

One definition used to study excessive crying in infants (colic) is crying for three or more hours per 24 hours. Excessive infant crying has been associated with a twofold increased risk of the overall problem behavior, conduct problems, hyperactivity, and mood problems at the age of 5–6. Excessive infant crying doubles the risk of behavioral, hyperactivity, and mood problems at the age of 5–6, as reported by their mother. Excessive crying is not the only factor in later childhood difficulties. Behavioral problems in childhood include the so-called regulatory problems, such as excessive crying, sleeping, and feeding problems, which occur in 20% of infants in multiproblem families. Excessive crying, whining and sleeping problems at 4–6 months are associated with decreased social development at 12 months.^[1]

Several factors may contribute to, and partly explain, an association between excessive infant crying and later behavioral and emotional problems. During early infancy, the quality of the mother–child dyad can be considered to be a crucial vehicle for child's healthy mental development. Both early maternal and early paternal reciprocity in infancy are predictive of social competence and lower aggression in preschoolers.^[1]

Compared to other infants, excessive crying infants had a slightly lower birth weight and a slightly younger gestational age. Excessive crying infants more often had a single, lower educated mother, originating from a non-industrialized country, who reported more depression, a higher burden of infant care, and more aggressive behavior and had an authoritarian parenting style. Excessive crying was associated with a higher risk for hyperactivity/inattention problems, emotional symptoms, conduct problems, peer relationship problems, and overall problem behavior at the age of 5–6, as well as a higher risk for decreased pro-social behavior as reported by the mother. Excessive crying was also associated with mood problems as well as generalized anxiety problems at the age of 5–6.^[1]

Abuse

Shaken baby syndrome

A common type of physical abuse in infants, shaken baby syndrome, is often a reaction to infant crying.^[30] Infant crying is a leading risk factor for shaken baby syndrome and other infant abuse.^[31][32]
