Dehydration in Children
Everyone needs water and certain chemicals (electrolytes) to be healthy. Normally, you drink fluids to meet the need, and being thirsty tells you when you need more fluids. But babies and very young children can't always tell you when they need fluid, especially when they're sick.
Dehydration is not having enough water in your body. Dehydration in children usually happens because of throwing up or diarrhea and the child isn't drinking enough to make up for it. Fever makes dehydration worse.
Throwing up and diarrhea can cause dehydration
Getting too little milk when breastfeeding can cause dehydration in babies

What fluids to give:
Breast milk, if you're already breastfeeding (breast milk contains electrolytes and is the best fluid for breastfeeding babies)
Oral rehydration solution (a combination of water and electrolytes) that you can buy as a powder or liquid at a drug store or grocery store—after your baby has gone 12 hours without throwing up, then you can give formula
