My child has really bad constipation. i have give her medicine and given her a suppository and still nothing, its going on the third day?

Increase water: Treating constipation at home involves increasing per day fluid intake (2.5 liters for female, 3.5 liters for male) including apple juice and prune juice, increasing fiber content of diet (more fruits and vegetables, apple/prune juice or fiber supplement), and using a stool softener for 1-3 days. Make sure not to strain as this can cause rectal hemorrhoids and bleeding)
