If your 2-year-old daughter is constipated and has only passed 3 large stool balls in a week and a half, it may be helpful to increase her daily dose of laxatives. It is recommended to give a dose of 12g per day for a child weighing 27 lbs. Additionally, increasing her intake of fiber-rich foods such as fruits and whole grains can also help with constipation. Dairy products do not contain much fiber, so they may not be as helpful in relieving constipation.
