How much oral rehydration solution does my child need?
Oral rehydration solutions consist of a combination of salts, water, and sugar and are used to replenish fluids and electrolytes that have been lost due to diarrhea and vomiting.
The amount of oral rehydration solution (Pedialyte®, Gastrolyte®) to give to infants or children is based on their age, as follows:
- infants 0 to 6 months old: 30 mL to 90 mL every hour
- 6 to 24 months old: 90 mL to 125 mL every hour
- 2 years and older: 125 mL to 250 mL every hour
Start by giving small amounts frequently (e.g., 5 mL every 5 minutes) and gradually increase the amount as tolerated.
