In children, diarrhoea will usually pass within five to seven days and will rarely last longer than two weeks. When a child vomits, it is often because their body is trying to get rid of germs or some other toxin.
Vomiting and diarrhoea can cause your child to lose a lot of fluid. This can be very dangerous, especially in hot weather or if they have a fever.
This is when your child’s stools become much more watery and more frequent than usual. There may be mucus or blood in the stools and they may be very smelly.
Almost all babies bring up a bit of milk without distress. This is normal. But if your baby is suddenly vomiting a lot more, or it occurs frequently over an hour or two, it could be serious. The vomiting may accompany other signs of illness, like fever or diarrhoea.
- Don’t try to manage it yourself – contact your doctor straight away
- Continue to breastfeed (small, frequent feeds are recommended)
- If you’re bottle feeding, stop giving formula. Instead, offer oral rehydration fluids or 50ml of boiled water, cooled to room temperature, every hour until you can see your doctor
- Continue to breastfeed. You may also offer 50– 100ml of clear fluids in between breastfeeds
- If you’re bottle feeding, stop giving formula for 12–24 hours. Give clear fluids instead. When vomiting and diarrhoea settles, or after 24 hours, recommence usual formula
- If your baby is on solids, stop for 24 hours, then slowly re-introduce them starting with rice, pasta, potato, toast or bread, or baby rice cereal. The aim is to return to a normal diet within two to three days of the illness settling
- Don’t give medicine unless instructed by your doctor
- Give oral rehydration solution (electrolyte solution) which you can get at your pharmacy – either in liquid form, or as sachets of powder that you mix with water. This helps to replenish important minerals such as sugar and salts
- If oral rehydration fluid is not available, fluids such as clear (without pulp), unsweetened fruit juice or cordial may be used with caution
