Smells a little of bad design. Consider putting the common methods for
Child1, Child2 into a module:

class Parent
end

class Child1 < Parent
  include ChildStuff
end

class Child2 < Parent
  include ChildStuff
end

Just a suggestion -- it's hard to really comment on a design without knowing
the problem you're trying to solve.
