This is an absurdly long time to have to force a child to fast.  It is
also cruel to both mother and child.  In places where anaesthetists
are experienced with children, the length of fasting before general
anaesthesia is 3 hours (Boston Children's, Philadelphia Children's, I
wish I could say Sick Children's Hospital in Toronto, but I can't,
though even in that haven of "only we know how to do things" the
length of fasting is 6 hours).

With six hours, it is possible, with scheduling the surgery for the
afternoon, to manage.  It is much easier to distract a child for six
hours during the morning than all night.

Here are a couple of articles which support short fasting times.

The following is a comment on the study:

If the dentist cannot manage a short fasting time, the mother would be
well advised to find someone else who can.
