Diana West told us about Niefert’s Rule of Fours for breastfeeding beginings. It is easy to remember:
4 yellow seedy stools
By the 4th day
for the first 4 weeks
By the fourth day, your mature milk will replace your colostrum. Your baby should also be past his meconium stools. Then your baby should have the yellow seedy stools of a breastfed baby. After the first four weeks, a breastfed baby will change his stooling patterns. He may have fewer or more than 4 stools a day. Until he’s a month old, use the rule of fours to help you decide if your baby is getting enough.
