Sure. Have a child at age 30. You will be 60 when the child is 30.

Yes! 
That occurs IN THE YEAR the child reaches the age that the PARENT was when the child was born.

Let me tell you even more:

     (Almost) every parent (under reasonable assumptions) once is exactly twice as old as his or her child.


Indeed,  if the parent brought a child when the parent was  X  years old,
then after  X  years the parent will be  2X  years old,  while the child  (the son or the daughter)  will be  X  years old
with the ratio of ages exactly  2.


The natural condition of feasibility is that they both are live at their corresponding ages.
