What about poop -- how much is too much?
Turns out, a baby's poop patterns are about as varied as weather cycles. After the first few weeks of life, it's perfectly normal for a breastfed baby to go seven times a day or once every seven days; formula-fed babies often poop somewhere between several times a day to once every two days, says Michael Steiner, MD, a pediatric expert at N.C. Children's Hospital at the University of North Carolina, at Chapel Hill. An infant's poop can be many different colors, but you should get it checked out if it's white or bloody. White can mean that the liver is having trouble metabolizing food, although this is not a common problem. And bloody stool can be caused by a number of things, such as an anal tear, allergens, even blood from Mom's cracked nipple.
