Infants don’t often develop full control of swallowing and the muscles of the mouth until they are between 18 and 24 months old, so drooling is normal in the first two years of life. Babies might also drool when they’re teething. Drooling is part of normal development in almost all children, however not every child stops drooling.

We produce more than 500mm of saliva a day – imagine not being able to control all that saliva. This is what happens to some children with disabilities or when there is impairment of nerves or muscles in the throat. Some examples include Cerebral Palsy, Down syndrome, head injuries, Muscular Dystrophy, seizures, and stroke. Drooling can also be caused by an underlying physical condition, such as enlarged tonsils, or by facial structure.

If your child cannot stop drooling, it is important that you speak to your paediatrician. Sometimes the problem requires more intensive medical intervention. Swallowing difficulties can result in life threatening problems, so always consult a physician to rule out any complications.

Saliva is produced around the clock in our mouths to aid speech by providing moisture to the mouth, assist eating by moistening food, and digestion by beginning the breakdown of food. Drooling occurs when saliva falls from the mouth as a result of an overproduction of saliva and/or problems controlling the saliva inside the mouth. Possible reasons for a lot of saliva in the mouth are:

  • The child might not be aware that they are losing saliva from their mouth
  • The child does not swallow often enough
  • The child maintains an open mouth posture or cannot close their mouth fully


If your child is facing this challenge, the following exercises can help to develop lip strength and coordination:

Blowing Bubbles – this is a great and fun way to help stop drooling. Practicing lip control will help your child to develop the strength, range of motion, and skill required to help with the problem of drooling.

Whistles – will help your child to practice the lip control they need to stop drooling. It may be noisy to your ears, but it’s worth it.

Straws – these require your child to use lower lip control and develop the facial muscles required to stop drooling. When appropriate, allow your child to drink from a straw, rather than a Sippy cup which can make drooling worse. If he needs help learning to use a straw, try using a juice box. Put the straw in his mouth and squeeze enough to give him a taste of what’s inside.

Cotton Ball – this is a good lip exercise. Place a cotton ball on a flat surface and have a race to see who blows faster and whose cotton ball goes further.
