Each child has dif­fer­ent bow­el habits. Not every child moves his or her vow­els every 24 hours. If, how­ev­er, your child has pain dur­ing bow­el move­ments, the stools are abnor­mal­ly hard, or there is mucus or blood (bright red or dark tar­ry), call the office. Some com­mon caus­es of con­sti­pa­tion are too much milk or oth­er dairy prod­ucts, or not enough wheat prod­ucts, veg­eta­bles and fruit in your child’s diet. Typ­i­cal­ly, a change in diet alone improves the situation.
