Get clear, parent-friendly guidance on what liquids are safest, when to offer small sips, and how to spot signs of dehydration if your child has a stomach bug or is throwing up.
Tell us how well your child is keeping drinks down right now, and we’ll help you understand what to offer, how much to try, and when dehydration may need more attention.
When a child is vomiting, hydration is usually the main concern. Start slowly. If your child wants to drink right away, offer very small sips instead of a full cup. Large amounts at once can trigger more vomiting. Oral rehydration solution is often the best choice because it replaces both fluids and electrolytes. If your child is asking for water, juice, or sports drinks, it may help to wait until they can keep down small sips consistently before offering larger amounts or sweeter drinks.
This is often the best fluid for child vomiting because it replaces water and electrolytes in the right balance. It is usually a better option than plain water alone when vomiting has been ongoing.
If vomiting is mild or improving, small sips of water may be okay, especially for older kids. Water can help, but it does not replace lost salts the way oral rehydration fluids do.
For children who vomit after most drinks, tiny amounts can be easier to tolerate. Ice chips, a spoonful every few minutes, or very small measured sips may help with rehydration.
Even if your child is thirsty, a full bottle or cup can lead to more vomiting. Slow, steady intake is usually easier on the stomach.
Juice, soda, and some sports drinks can be hard on the stomach and may worsen diarrhea if a stomach bug is involved. They are not usually the first choice for oral rehydration.
Heavy drinks can be harder to tolerate right after vomiting. If your child is still throwing up, simpler fluids are usually a better place to start.
Fewer wet diapers, going many hours without peeing, or very dark urine can be signs that your child needs more fluids.
A dry tongue, cracked lips, or crying without tears can point to dehydration, especially if vomiting has continued for several hours.
If your child seems unusually sleepy, weak, dizzy, or less responsive, dehydration may be more serious and should be assessed promptly.
There is not one exact amount that fits every child. What matters most is whether your child can keep fluids down and gradually increase intake. Start with small sips every few minutes. If that stays down, continue slowly and build up over time. Toddlers and younger children often do better with tiny, frequent amounts rather than bigger drinks. If your child cannot keep anything down, is vomiting repeatedly, or is showing signs of dehydration, it is important to get more guidance.
The safest first option is often an oral rehydration solution in small sips. If your child is improving and keeping fluids down, small amounts of water may also be okay. Avoid giving a large drink all at once.
Offer very small amounts frequently, such as a spoonful or sip every few minutes. Toddlers often tolerate tiny amounts better than cups or bottles. Oral rehydration fluids are usually the best choice when vomiting has caused fluid loss.
Watch for fewer wet diapers or bathroom trips, dry mouth, no tears, dark urine, unusual sleepiness, or weakness. These can be signs of dehydration, especially if your child is not keeping fluids down.
Oral rehydration solutions are usually preferred because they are made for children and have a better balance of fluids and electrolytes. Some sports drinks are too sugary and may not be the best option right after vomiting.
If your child vomits after most drinks, try even smaller amounts, such as a teaspoon or spoonful at a time. If your child cannot keep anything down or seems dehydrated, they may need medical advice sooner.
