my 5 month year old baby girl is starting to have soft stools like mashed potatoes. sorry to compare it to food. but it's coming back to normal when I switched her formula back to the one she had first used as a newborn. but I'm still going to buy prune and pear juice. incase she goes back to having hard stools. my nurses recommended it anyways. and said it's normal at that age for hard stools/constipation.
