Hi, Welcome to icliniq.com. Many thanks for your query. Very often we put down these symptoms to teething, but this usually is a viral illness - a viral upper respiratory tract infection (URTI). Teething by itself does not cause these symptoms; it is just that it is at the same age that they start teething that they get the more viral illness, as the mother's antibody in the child's blood dies down, and the child has not yet grown their own antibodies. So it is a coincidence, rather than a cause.
