Each dose is 2 teaspoons, which is equivalent to 10 mL (since 1 tsp = 5 mL). Each child receives 3 doses per day (24 hours / 8 hours per dose), which totals 30 mL per child per day (3 doses * 10 mL per dose). Over 5 days, each child will need 150 mL (30 mL/day * 5 days). For 3 children, this amounts to 450 mL (150 mL/child * 3 children). Since each bottle contains 150 mL, 3 bottles are needed to have enough cough syrup for all 3 children for 5 days.
