Dilute apple juice with water to achieve 50:50 mix. Other preferred fluids can be used at the same dilution.
During the consultation, give the child 5 mL aliquots to drink every 2–5 minutes from a spoon or a 5-mL syringe. Continue this at home while symptoms persist and/or until urine output is restored.
As a guide, the child should be given 10 mL/kg for each episode of diarrhoea or 2 mL/kg for each episode of vomiting.
If vomiting and diarrhoea have stopped before rehydration treatment is started, continue rehydration until restoration of normal urine production. (Restoration of hydrated body weight can also be used, but this is rarely known with enough accuracy.)
