My 9 month old has always had normal, regular stools. But, yesterday she didn t have her early morning stool. Later she had a little pile of hard pellets of stool (the size of peas or larger). A few hours later she had a watery stool. You could tell that almost clear fluid had come out and absorbed into the diaper leaving flecks of stool and partially digested food (there was a whole pea) on the diaper. She has not had a stool in the last 24 hours since this. She was up every 30 minutes crying last night until 1:30 a.m. Is this a normal episode of constipation, or should I be concerned about a blockage or fecal impaction?
