Re: Bowel Movements
After 6 weeks it is quite common for breastfed babies to go as much as a week, sometimes more, between poops. This is possible because breastmilk is so easily and completely digested that there is very little waste left over to excrete. This is very different from the elimination patterns of formula-fed infants. Formula contains so much indigestible material that formula-fed babies should poop every day or so, though they often do not because formula causes constipation.
When a baby is constipated, she will be in severe discomfort when pooping (screaming, crying, turning red with effort), and the poop will be dry, hard, pellet-like, and solid enough to to roll right out of the diaper if you pick it up. If baby's poop is soft, liquid, or peanut-butter consistency, it's not constipation poop. That doesn't mean that baby won't make effortful noises and faces when trying to pass stool or gas. It takes babies a while to adjust to the normal workings of their digestive systems. Think about it this way: if you had never passed gas or pooped until 8 weeks ago, you'd still be kind of upset by the process, wouldn't you?
Your baby will grow out of her grunting, pushing, and farting as her muscle tone improves and she learns how to get a poop/fart out without as much work. Just be patient with her, and if she seems really uncomfortable try popping her in a warm bath or doing some gentle tummy massage.
