In brief: Med takes longer

Miralax (polyethylene glycol) is a wetting agent not a laxative.
Relief from the discomfort of constipation is best done with a washout of the rectal vault & sigmoid colon using an enema or stimulant suppository like ducolax. Miralax (polyethylene glycol) will take about 3 days to work its way through the system if the kid is having bowel movements.It's longer term use over weeks to months may help fix the issue.
