Aloha Kathy, I tell moms that starting about 6 weeks of age many babies do not stool as often as the 2-5 stools per day in earlier weeks that were to be expected. Some may stool once every two-three days or once a week. This is in the realm of normal for breastfed babies. For all three of my children, starting at 6 weeks, they would only stool once a week. That one day a week I refered to as their pooping day as that is all they did! It seemed that once they weaned from the breast their norm came to be once a day thereafter.
