Dehydration

1 min read

Pediatrician

Babies get dehydrated quickly with vomiting, diarrhea, fever or heat. The key is to give fluids little by little, and often.

What to do

  1. Keep breastfeeding or giving formula, and more often.
  2. If the baby is vomiting or has diarrhea, give infant oral rehydration solution (such as Pedialyte) in small amounts: 1 to 2 teaspoons (5 to 10 mL) every few minutes, with a syringe or spoon. If the baby keeps it down, slowly give more.
  3. If the baby already eats solids, continue normal foods in small portions when hungry.
  4. Count wet diapers and write everything down.
  5. If things don't improve in a few hours or a warning sign appears, call or go to the ER.

What not to do

  • Don't give plain water to a baby under 6 months.
  • Don't use juice, soda, sports drinks (like Gatorade) or tea to rehydrate.
  • Don't make homemade rehydration drinks or water down formula.
  • Don't give anti-diarrhea medicine unless the pediatrician says so.
