Insights
Breastfed infants have more frequent, softer, yellow stools than formula-fed infants in the first three months. Green stools are normal for formula-fed infants, with frequency decreasing over time.
Area of Science:
- Pediatrics
- Infant Nutrition
- Gastroenterology
Background:
- Defecation issues are common in infants, necessitating a clear understanding of normal patterns.
- Establishing baseline defecation data is crucial for identifying abnormal infant bowel movements.
Purpose of the Study:
- To characterize the typical defecation patterns in healthy Dutch infants.
- To provide normative data on infant bowel movements for clinical reference.
Main Methods:
- A cohort of 600 healthy Dutch infants was selected from a larger group of 1175.
- Parents meticulously recorded feeding and defecation details at 1, 2, and 3 months using standardized tools.
Main Results:
- Breastfed infants exhibited a significant decrease in daily stool frequency from 3.65 to 1.88 within 3 months.
- Breastfed infants had higher stool frequency and softer, yellow stools compared to formula-fed infants.
- Formula-fed infants frequently had green stools by 3 months, which is considered normal.
Conclusions:
- This study presents defecation patterns for the largest cohort of healthy infants to date.
- Breastfed infants show distinct stool characteristics (frequency, consistency, color) compared to formula-fed infants in early life.
- Green stools in formula-fed infants are a normal finding and should not be a cause for concern.
Background:
Defecation problems occur frequently in infants. A clearer insight into the normal defecation pattern is required to gain a better understanding of abnormal defecation.
Aim:
To describe the defecation pattern of healthy infants in The Netherlands.
Methods:
From a research population of 1175 healthy Dutch infants, 600 infants without any complaints were selected. The parents recorded details of feeding and defecation at the age of 1, 2 and 3 months using a standardised questionnaire and bowel diary.
Results:
In breastfed infants, average daily defecation frequency decreased significantly during the first 3 months (from 3.65 to 1.88 times per day), whereas no significant changes were observed in infants fed standard formula or mixed feeding. At every age both the average and the range of defecation frequency of breastfed infants were higher than those of infants receiving formula feeding. Breastfed infants had softer faeces than formula-fed infants and the colour more often was yellow. At the age of 3 months, 50% of stools of formula-fed infants were green coloured. There was no significant difference in quantity between the three types of feeding, but there existed a negative correlation between defecation frequency and quantity.
Conclusion:
This study gives insight into the defecation patterns of the largest cohort of healthy infants published so far. In the first 3 months of life, breastfed infants have more frequent, softer and more yellow-coloured stools than standard formula-fed infants. Green-coloured stools in standard formula-fed infants should be considered normal.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
