As some young children can’t speak and are unable to tell when they are thirsty or when they need a drink of water, it is therefore extremely important that parents know the recommended fluid intake for Young children and try to incorporate this into children’s daily diet. Young children need relatively small amounts of fluid, while older children need more amounts of water per serving. 
|Recommended fluid intake for younger and older children|
|Age category||Amount of fluid per serving|
|Younger Children – 5 to 8 months||150 ml|
|Older children – 8 to 11 months||250 ml to 300 ml|

It is useful to use a sippy cup with the capacity of the recommended fluid intake or measurement scales which tell you how much your child is drinking.
Water is the best and most healthiest form of hydration for children.
Avoid putting juice in sippy cups, especially cups with straws as it’s not always easy to clean such parts of the cup thoroughly.
