They start to cry at 2 in the morn
      To have their firstly feed.
Their pants are full of nasty stuff
      Why do they do this nasty deed?
And you think Oh why did we do this?
      Is it something we really need?

But then they take their first wee steps
      Their smile lights a darkening sky.
They utter a word and play with your thumb
      And chuckle and gurgle and sigh.
And you watch amazed at their quickening growth
      ... and you know the reason why.
