When babies are teething, it can be frustrating. Babies are fussy, in pain and sometimes have other symptoms. Most babies will start getting their first teeth between 4 and 7 months old. Babies' teeth develop beneath the gums while they are in the womb and will break out one at a time. Many times the first are the bottom two teeth followed by the top. By the time a child is 3, they will have a set of 20 baby teeth.


Many parents find their babies experience many different symptoms while teething such as excessive drooling, fussiness, sleep problems and biting. Diarrhoea is also often related to teething. There is some discussion as to whether these symptoms are caused by teething, or coincidentally seem to happen at the same time, according to

Diarrhoea and Teething

Diarrhoea is common in infants and includes an increased number of bowel movements and loose stool. If your child is having more than three loose bowel movements a day, he may have diarrhoea. Many times children with diarrhoea have other symptoms such as fever, irritability or fatigue.

Excess Saliva

Paediatrician and author William Sears feels teething does cause diarrhoea, which may also cause a diaper rash. Sears contends that the excess saliva the child produces when teething may settle in the stomach causing diarrhoea.

Teething Stress

Many child development experts, such as Penelope Leach, feel that symptoms such as diarrhoea and fever are a sign of illness that happen at the same time as teething. Stress the child is going through due to teething may make it more susceptible to becoming sick.

No Scientific Proof

Dr. Vivian Lennon of Children's Hospital in Atlanta feels teething and diarrhoea are not connected and a connection has not been scientifically proven, according to She feels that children often have unrelated illnesses during teething and that the teething is blamed for the other illnesses.
