Teething begins at the age of 4–6 months and goes on in phases till about 12 years of age. However, it is important to note that when the teething phase begins, a baby is also be achieving other milestones – crawling & exploring more, starting to eat solid food, etc. And as these highpoints coincide with teething, parents easily mistake any issue that the baby faces as one of the symptoms of teething.
Now if you take the example of a baby that has started consuming solid food as the teething phase has begun, his/her stomach may take time to adjust to it and react through vomiting or diarrhea.
Similarly, as the baby has started crawling, he/she explores objects with the hands and mouth and an unclean object in the mouth can cause an infection giving rise to vomiting, fever, diarrhea, or even skin rashes. So these issues are not related to teething directly…!!!
Also according to AAP – American Academy of Pediatrics the antibodies that the baby gets from the mother at the time of birth start fading too at about this age, making the baby more susceptible to bacterial and viral infections.
In an indirect connection to teething, babies tend to drool more while teething, which on contact with skin can cause skin rashes or diarrhea.
Thus, vomiting in babies can be caused due to a bacterial or viral infection during the teething phase (possibly because of the excessive drool or due to contracting bacteria while crawling, gnawing etc.), which can get very stressful for the child and parents.
To understand and handle teething vomiting/ nausea while teething, lets first understand what are the various causes that lead to vomiting.
Now let us understand what exactly causes vomiting in babies.
