Design outcomes

Primary

MeasureTime frame
1. Faecal microbiota composition of the mothers and neonates. The faecal microbiota composition of the mother will be measured 2 times (with one week interval) between 1 and 2 months before the delivery. The faecal microbiota composition of the neonates will be measured in the first faecal sample of the neonates and two days later, and at one week, one month, 3 months and 6 months of life. If the baby starts with weaning food during the study period, 1 faecal sample needs to be collected 1 week after start of weaning. 2. Faecal short chain fatty acids (SCFA) and faecal lactate, measured at the same timepoints as that of the faecal microbiota 3. Microbiota composition of the breast milk. The microbiota composition of the breast milk will be measured before delivery when possible, and after delivery (colostrums) if possible, at 1 week and 1 month after delivery. 4. Oligosaccharides quantification in breast milk, measured at the same timepoints as that of the breast milk microbiota 5. Lipid quantification in breast milk, measured at the same timepoints as that of the breast milk microbiota 6. Protein quantification in breast milk, measured at the same timepoints as that of the breast milk microbiota
