The data were submitted to statistical analysis - chi-square test and Fisher's exact test, with a significance level of 5%.

Results: When correlating the data, the statistical analysis revealed an association between ankyloglossia and the items of suckling category of the Breastfeeding Observation Aid. The association between complaint of difficulty in breastfeeding and ankyloglossia was also seen.
