There are many reasons why children can get dried out or dehydrated. A child can lose too much liquid from the body from diarrhea, vomiting or fever. If the child has mouth sores or a bellyache, they may refuse to drink enough. Babies and younger children are at greater risk.
Getting dehydrated can be dangerous for infants and young children. They may not get enough electrolytes (salts) needed for their body to work the right way. If the liquids are not replaced, the child may need to have an IV (fluid given directly through a plastic tube into the vein or intravenously) to rehydrate them. We do not think your child needs an IV right now.
Kinds of Liquids to Give
Your child may need to drink an ORS (oral rehydration solution) like Pedialyte® to help prevent dehydration. An ORS replaces the electrolytes and fluids that your child needs. Sports drinks and home remedies should not be used instead. ORS store brands are just as good as a brand name. You can buy ORS in liquid or powder form or as popsicles at most pharmacies without a prescription.
ORS should not be given as the only fluid for more than 6 hours. Do not dilute or mix an ORS with formula.
Do not give fruit juices or liquids that are high in sugar, such as Hawaiian Punch®, Hi-C®, Kool-Aid®, sodas or syrups. Do not give teas or broths. These liquids do not have the right mix of electrolytes and can make diarrhea worse.
For babies younger than 12 months: Give breast milk, ORS or formula (if tolerated). Do not stop breastfeeding. Do not dilute formula.
For children over 1 year: Give the same kinds of liquids as above and water. If needed, you may hold back on milk for 1 or 2 days until your child’s vomiting or diarrhea begins to improve. Avoid red-colored foods or drinks that might look like blood in diarrhea or in vomit.
How to Give Liquids
If your child is sick to their stomach or dehydrated, give small sips of ORS, breast milk or formula (if tolerated) every 5 to 10 minutes. Start by giving babies 1 teaspoon (5 mL) of liquid.
For toddlers and children, give 1 tablespoonful or 3 teaspoons (30 mL). Gradually work up to drinking more. Even if your child vomits some, most of the liquid is kept down. Wait for 30 to 60 minutes and try to give small amounts of liquids again.
Goals for Giving Liquids
Measure the amount of liquid your child needs based on their weight. If your child can not sip from a cup, try using a teaspoon or a syringe.
|Child's Weight||Minimum Goal to Give Every Hour*|
|7-10 lbs.||At least 2 ounces (4 tablespoons or 1/4 cup)|
|11-15 lbs.||At least 2-1/2 ounces (5 tablespoons)|
|16-20 lbs.||At least 3-1/2 ounces (1/2 cup)
|21-40 lbs.||At least 6-1/2 ounces (3/4 cup)|
|41-60 lbs.||At least 10 ounces of liquid every hour (1-1/4 cups per hour)|
* Minimum fluid goals per hour may increase if vomiting, diarrhea or fever are present.
