Literature review for - Flourish Paediatrics

Among those 1 to 6 month so age, 1 month old infants appear to have the highest prevalence
(Herman and Le 2007).
Management of excessive, unexplained infant crying
No evidence base was developed for the management of excessive, unexplained crying due to
the lack of quality studies.
A cohort of 700 healthy breastfeeding mother–baby dyads in the USA revealed 82 % of
women at 16 weeks found breastfeeding was a highly effective calming practice for a crying
infant. The study also found that the use of breastfeeding to comfort infants was a significant
predictor of longer partial breastfeeding (but not exclusive or full) duration; HR 0.6 (0.4, 0.9)
(Howard, Lanphear et al. 2006).
A cross-sectional study including 5845 Dutch infants compared infant crying in smoking and
non-smoking parents. The results showed that infants whose parents were heavy current
smokers or whose mothers had been so during pregnancy had a higher prevalence of
excessive crying than infants of non-smoking parents; OR 1.80 (1.26, 2.57). In response to
their findings the authors indicate parents stopping smoking may reduce excessive infant
crying (Reijneveld, Lanting et al. 2005).
