When is a child constipated?

According to the American College of Gastroenterology, the number of regular stools varies significantly in children, from three times a week up to 3 times a day. Constipation is a frequent and often frustrating problem for children. When a child goes out for four days or more without a bowel movement or has hard or painful stools, an intervention may be necessary.

In most cases, constipation is not linked to other diseases. The first stages of treatment for children with constipation include changes in behavior, such as sitting on the pot for five to ten minutes after each meal and getting positive reinforcement with rewards, as well as dietary changes, such as drinking more water or high fiber foods like bran, fresh fruits,whole wheat, and vegetables.

When should a child use Miralax?

If constipation does not get greater with changes in routine or food, the child should see his doctor before starting a medicine like Miralax to soften the stool. Although the drug is available over the counter, parents should not use a laxative in young children without talking with the child’s doctor.

How does the Miralax work?

Miralax is a white powder that dissolves in a cup of water or juice. The dose for children is usually 0.7 to 1.5 g / kg/day dissolved in 4 to 8 ounces of water, up to a maximum dose of 17 g c. Soup, per day. Two to four days of treatment may be needed before Miralax works.
