    The Miralax dosing information says “ask a doctor” for < 17 years old. However, many drug references including the PDR give off-label recommended dosing for infants (~0.5 to max 1 gm/kg/day). A retrospective cohort study of usage in the UK in 13,275 children < 2 years old identified use in 477 0-6mo olds and 3,378 6-12 mo olds. There were no confirmed electrolyte disturbance events.
