The aim of this review is to identify the behavioural soothing interventions (BSIs) used for reducing infant crying and to determine their effect. Studies had to describe an experimental study addressing infant crying and BSIs in the first six months after birth. Searches were performed in Web of Science, Pubmed, Science Direct, EBSCOhost, PsycINFO, and COCHRANE. It was determined from the studies that massage, spinal manipulative therapy, and occipito-sacral decompression have a positive effect on the soothing of crying behaviour in infants. It was determined that BSIs are most effective when applied before the 8th week and that certain BSIs are effective in reducing the crying duration. It was revealed that there is a need for a standard data collection tool for the determination of the crying duration. Professionals interested in child health should be aware of irregularities in the crying of infants in the early period.
