Background and Aims Routine follow-ups of healthy newborns for up to 48 h for those delivered by normal vaginal delivery (NVD) and for up to 96 h for those delivered by cesarean section (CS) are highly recommended as they facilitate the early detection of certain problems.

Objectives To investigate the meconium/stool and urinary patterns of healthy Turkish neonates, and to determine whether they correlate with delivery mode, birth weight and feeding method and frequency.

Methods Newborns with a gestational age of ≥ 34 wk were included. The frequency of meconium/stool and urine passage and the delivery mode, birth weight and feeding method and frequency were recorded throughout their hospital stay.

Results A total of 1,095 newborns were included. Within the first 24 h, 99.2% and 90.4% of the newborns passed their first meconium/stool and first urine, respectively. The number of meconium/stool and voidings was higher in the CS group. The number of meconium/stools within the first 24 h was higher in exclusively breast-fed newborns. Combination-fed newborns and newborns with a lower birth weight had a higher number of voidings. The number of meconium/stools in the first 24 h was significantly lower in newborns weighing < 2,500 g. Furthermore, breast feeding frequency correlated with the number of meconium/stools and voidings at all time points.

Conclusions The results of this study show that the mode of delivery, birth weight and feeding method and frequency and may influence meconium/stool and urinary patterns in newborns.
