Biology:Infant sleep training

From HandWiki

Sleep training (sometimes known as sleep coaching) is a set of parental (or caregiver) intervention techniques with the end goal of increasing nightly sleep in infants and young children, addressing “sleep concerns”, and decreasing nightime signalling. Although the diagnostic criteria for sleep issues in infants is rare and limited, sleep training is usually approached by parent(s) or caregivers self indentifying supposed sleep issues.[1] The idea of early independence and sleep training in babies was promoted by Dr. Luther Emmett who published The Care and Feeding of Children in 1894. This is widely believed to be the basis from which, modern sleep training has evolved.

Popular methods of sleep training include extinction or “cry it out”, Ferber, The Chair Approach, and more improvised “gentle” methods.

Sleep training tends to be popular in countries such as the USA and UK, and is mostly unheard of in societies that practice cultural cosleeping.[2]

The development of sleep over the first year

Main page: Biology:Infant sleep

During the first year of life, infants spend most of their time sleeping. An infant can go through several periods of change in sleep patterns. These can start at 1 week, occurring weekly or fortnightly, until 8 years of age due to innate and external factors that contribute to sleep.[3]

Developing infants also sleep within a large spectrum of sleep — falling into high and low needs categories — fragmented through 24 hours.[4][5]

These frequent night awakenings are an evolved trait, to feed frequently and playing a part in SIDS protection. However, this can be disruptive for the parent(s) or caregiver — for example, if maternity leave is non-existent or they feel the benefits of an undisturbed night can help with severe sleep deprivation. Parents who sleep trained perceive improvement in infant sleep.[6]

Good sleep conditions

Sylvia Bell of Johns Hopkins University reported:[7] by the end of the first year individual differences in crying reflect the history of maternal responsiveness rather than constitutional differences in infant irritability. She also notes: consistency and promptness of maternal response is associated with decline in frequency and duration of infant crying. When following through with this maternal response, Bell notes that it is most effective to apply physical contact with the infant.[8]

The sleep position is also important to prevent Sudden Infant Death Syndrome (SIDS).[9] It is recommended that the proper position for children to sleep in to avoid SIDS is laying on their back throughout the night. Their bedding should be firm and crib should be free from toys or blankets that could cause injury or suffocation to the child. Loose blankets and toys in the crib can increase the child’s risk of SIDS.[10]

Controversies in sleep training

Sleep training in a separate room, under 6 months is not recommended due to the SIDS reduction factors at play. A committed caregiver in the same room for all day and night sleeps reduces the risk of SIDS by 50 per cent.[11]

These guidelines for baby being in the same room differs from 6 months to 12 months in different countries.

The ECAS study attributed 36 per cent of total SIDS deaths to sleeping alone in a room.[12]

Another key debate in sleep training revolves around getting the right balance between parental soothing and expecting baby to be independent. Attachment parenting is a parenting philosophy characterized by practices such as baby-wearing (carrying infants in slings or holding them frequently), long-term breastfeeding, co-sleeping (sharing the parental bed with the baby), and promptly responding to a baby's cries.[13] Popular sleep training methods, such as the Ferber Method, rely on letting the baby cry for a certain number of minutes, to allow the child a chance to fall asleep more independently and move away from an over-reliance on parental assistance to fall asleep. Advocates of attachment parenting generally reject traditional sleep training methods that involve allowing a baby to cry, asserting that such practices do not align with meeting the child's immediate needs.[13]

A study conducted also showed that sleep trained babies displayed elevated cortisol levels (a proxy for stress, although this study did not have control babies without sleep training), but were simply not signalling to their parents.[14]

Another method is Behavioral Infant Sleep Intervention to effectively reduce infant sleep problems and associated maternal depression in the short- to medium-terms. This method randomized tried and found effective at reducing the short- to medium-term burden of infant sleep problems and maternal depression [15]

One study shows that 80% of infants from Asian countries shared a room with their parents. These parents reported less overall sleep compared to the Caucasian countries where 50% of infants were reported to be sharing a room with their parents during the infants' first couple months of life.[16]

One study reported parents waking up in the night less and feeling more parental competence in the group that was taught these behavioral techniques.[17]

Sleep coaching industry has been criticized for being unregulated, suffering from excessive fees.[18]
