Dehydration in Babies and Toddlers


Diarrhoea is a leading cause of child mortality in the world, responsible for killing around 760 000 children every year5. Most children who die from diarrhoea actually die from severe dehydration and fluid loss5, as babies’ smaller bodies have smaller fluid reserves and a high metabolic rate, which makes it easier for them to lose the water and electrolytes needed for their bodies to function. If fluids are not replaced, the outcome can be critical within a few days so it is best to take action sooner rather than later.

  • Even while a baby’s diarrhoea or vomiting persists, keep offering him/her small amounts of water or REHIDRAT® at regular intervals as some will be retained by his/her body.
  • Because sick babies often refuse to drink anything when they are ill, some moms put the solution into a syringe and squirt a small amount gently into the side of the baby’s mouth. Care should be taken not to squirt the liquid into the back of the throat or squirt too much, too quickly as this may cause a baby to gag or choke.
