While we can’t promise to make the whole ordeal fun, we can help give you the peace of mind of knowing how to best care for your child.
Usually, vomiting is caused by viral gastroenteritis, also known as the “stomach flu.” Two of the most common culprits are norovirus and rotavirus. Norovirus is transmitted by touching surfaces contaminated by poop or vomit. You can get norovirus by doing things like eating contaminated food, putting your fingers in your mouth after touching a contaminated surface, or by sharing utensils or food. The best way to decrease the spread of the virus is good hand washing and cleaning contaminated surfaces.
Are Stomach Flu and Influenza the Same Thing?
The “stomach flu” often gets confused with influenza (commonly called the flu) but is different. The “stomach flu” is a viral infection in your stomach or intestines. But Influenza, or the flu, is a viral infection in your nose throat and lungs, and includes symptoms like a fever, sore throat, cough, body aches, and stuffy nose. Some people also vomit when they have influenza.
Usually, vomiting isn’t serious and can be treated at home, but you will want to be careful about dehydration—which can be very dangerous.
Children of Any Age:
If your child has a headache, is excessively thirsty, hasn’t urinated in over 10-12 hours, doesn’t produce tears when crying, or complains of a dry mouth, please call us right away. Dehydration is a serious condition that can escalate quickly.
Dehydration is especially dangerous in very young children and infants. Check frequently for signs of dehydration and seek help immediately if you cannot keep your child hydrated or if you are in any doubt or have concerns about their condition.
Dehydration is the most serious complication from diarrhea and vomiting. During those first few hours, your main goal will be to help your child keep down small amounts of fluid to prevent dehydration. Even if children continue to vomit or have diarrhea, they are still absorbing and retaining some of the fluid you give them. Next to staying hydrated, the most important thing you can do for your child is to allow for plenty of rest and sleep. Sleeping can help empty and settle the stomach.
Children over one-year-old: Offer small amounts of clear fluid—about 3 teaspoons—every five minutes. Try chilled Pedialyte. Other options are half-strength Gatorade, popsicles, clear broth, or flat lemon-lime soda and ginger ale. If your child has been vomiting for more than 12 hours, you will want to use an oral rehydration solution to help restore some of the salts and sugars that have been lost.
Don’t let your child drink anything too quickly as this can trigger vomiting again. For the next few hours, you are going to want to take it slow. If your child continues to vomit, wait about 30 minutes and try again. Once your child hasn’t vomited for 3 to 4 hours, gradually increase the amount of fluids.
Breastfed babies: Breastmilk is the perfect food for sick babies. It is easy for them to digest, is comforting, and contains lots of antibodies. Babies who only vomit once can continue breastfeeding as usual. If your baby vomits again, you will want to reduce the amount of breastmilk your baby is getting each time by nursing for about 5 minutes, every 30 to 60 minutes. If your baby hasn’t thrown up in 4 hours, you can return to normal nursing. If your baby continues to vomit breast milk, then use an oral rehydration solution (Pedialyte) but do not use water.
Bottle-fed babies: If your baby is formula-fed and throws up more than once, you will want to use an oral rehydration solution, not water. For the first 4 hours, offer 1 to 2 teaspoons every 5 minutes. You can double the amount after your baby hasn’t thrown up after 4 hours. After 8 hours, you can return to regular formula.
When your child stops vomiting, you may resume a normal diet. If you child has diarrhea you may want to use lactose-free milk and low lactose foods. Probiotics like Culturelle may also speed recovery.
If your child has a high fever and is vomiting you can ask the pharmacist about using an acetaminophen suppository. If your child throws up a prescription medication, contact your doctor to find out what to do. Sometimes a prescription for Zofran can help decrease nausea and vomiting.
One of the worst parts about the stomach flu is waiting to see who will get it next. However, there is a lot you can do to prevent it spreading. Since noroviruses are spread through ingestion, if you are careful about what goes in your mouth, you stand a better chance of not getting it.
People are usually contagious when they start to feel sick and for a few days after they recover. The norovirus can also survive for days on surfaces. You will want to be careful even after the storm has passed. It isn’t uncommon for one family member to get sick and then have somebody else get sick five days later.
When disinfecting, focus on the kitchen, commonly-touched surfaces, and the laundry. Noroviruses are hardy and can withstand hot and cold temperatures as well as many disinfectants.
Hand sanitizer isn’t going to cut it—you will need to wash with soap and water.
Streamlining clean up can also make it easier to keep things disinfected and clean. For example, keep a bucket, large bowl, or pitcher at the ready in case your child needs to vomit. Kids are notorious for not making it to the toilet in time and it will make your life a lot easier if you aren’t having to clean the mess up off the carpet, bed, or couch. Little kids still might miss, but most kids don’t want to be covered in vomit any more than you do, so they will learn quickly.
And as tempting as it is to assume that your kid won’t throw up when they are complaining of an upset stomach, it is better to be safe than sorry. Vomiting can come on quickly and once it starts, it is already too late. Save yourself from a lot of disgusting clean up by preparing for the worst even if you are hoping for the best.
It is also a good idea to cover the area by the bed with towels or sheets to protect the carpet. Have some clean sheets handy for changing the bed when you need to. Some parents even use large towels instead of blankets because they are more absorbent. A towel over the pillow is also helpful. Pulling long hair back into a bun or braid is also a great idea and could save you from the unpleasant task of picking vomit out of hair.
A little foresight will not only make life a lot easier for you but will make it less likely that the virus will spread to other members of the family.
Most often, vomiting lasts less than 24 hours and your child will be back to her old self quickly. Occasionally, children will vomit off and on for up to a week. This is ok if they are eating and drinking well most of the day and not dehydrated.
Give your pediatrician a call if vomiting lasts more than 24 hours, if vomiting is a frequent problem, or if your child has been vomiting clear fluids for more than 8 hours.
