How to get a GameObject to follow an instantiated object then when a new one spawns follow the new Instantiated object

Here is my problem, i have code written to instantiate an object and i have a spawner that i want to follow it on the Y axis and when that object gets to the bottom i want the spawner to attach to the new object and follow it down repeat the over and over again.

I came up with an answer based from a Question by Der_Kevin · Dec 07, 2015 at 03:28 PM · camerainstantiatespawn
set instantiated object as Transform target?
