Looks like a case for allow_nil:
validates_numericality_of :children, :allow_nil => true
The documentation at
http://ar.rubyonrails.org/classes/ActiveRecord/Validations/ClassMethods.html#M000091
mentions
:allow_nil - Skip validation if attribute is nil (default is false).
Notice that for fixnum and float columns empty strings are converted to
nil.
