This is the default behavour:

"The children of a supervisor is defined as a list of child
specifications. When the supervisor is started, the child processes
are started in order from left to right according to this list. When
the supervisor terminates, it first terminates its child processes in
reversed start order, from right to left." (from
http://www.erlang.org/doc/man/supervisor.html)
