Methods: observational, analytical, quantitative case-control study. For the evaluation of non-nutritive sucking, the PROFAS protocol was used and for the evaluation of performance at the mother’s breast, the protocol of Speech Therapy - Breastfeeding. The sample was stratified into two groups, the experimental group, composed of newborns of mothers diagnosed with GDM, and the control group, with newborns of healthy mothers. For statistical analysis, the Mann-Whitney, Shapiro Wilk and Student’s t tests were used. Results: the total sample consisted of 46 newborns, 21 from the experimental group and 25 from the control group. P<0.05 was observed in the comparison between the groups in the variables: oscillation in the state of consciousness, global hypotonia, weak search reflex, less than five suctions per pause in the assessment of non-nutritive sucking, holding on to the breast, falling asleep after starting suction and mother-infant positioning. Conclusion: newborns of mothers diagnosed with GDM had greater difficulty in readiness for oral feeding and in the practice of breastfeeding in the first 72 hours of life, compared to children of healthy mothers.Attribution-NonCommercial 3.0 Brazilhttp://creativecommons.org/licenses/by-nc/3.0/br/diabetes gestacionalaleitamento maternocomportamento de sucçãomacrossomia fetalarticlehttps://doi.org/10.1590/2317-6431-2022-2721pt
