Most babies start teething anywhere from 3 and 7 months old.  In special cases a newborn could have a tooth at birth or could be as late as a one year old.  Teeth can break through one at a time or several can come through at once.  For some of the lucky babies there are no teething signs at all but for most there is some level of discomfort.  The most common signs of teething can be refusing to eat, pain waking them from sleep, drooling and gnawing.  Soothing your babies pain can be as simple as buying a rubber teething ring which you keep in the fridge or freezer for them to chew on or it can be as extreme as soothing gel that you buy from the chemist.  Just keep reminding yourself that it won’t last forever and is part of natural progression.  By the time your child reaches the age of 3 he or she should have a full set of 20 baby teeth.  Their permanent teeth should start coming in around aged 6 and they shouldn’t fall out until then.
