Birth of Depression

I have been thinking of all the attention
      we give a first/only born.
We are going to do this right
    Raise them better than we were raised.
Create this little perfect human.
        Teach them like we wish we were taught.
Immediately stop any negative traits

We wonder at their inate intelligence
  Try to see that they are happy, always
Shower them with attention
   Praise each step of growth….

Then the second child is born…
      Or life happens and we change jobs
           Or issues with our partner
               Or somebody gets very sick
                    Or dies….

And we become distracted from our worship and wonder of this child.

They might begin to feel extra,
Unnecessary, 
         in the way,
                    unimportant…
Sadly, begin to doubt their worth.
      Feel under-valued…
               Less than……
Not understanding the disconnect
Has nothing to do with them.

Could this possibly be the source, the birth of deression?
