The addition of fiber is anticipated to allow children to have more normal stool consistency and frequency.~All participants will be asked to take a snack bar twice daily and will be randomized in a 1:1:1 ratio to fiber 1, fiber 2 or placebo snack bar groups. All participants will be asked to take low-dose Miralax to avoid worsening of constipation in all groups.
