This song was written by lead man Brendan Bayliss. He started writing a song for his first child, and it ended up being a love song for his wife.

If you want to try and step into another kind of shoe I’ll be right behind
And he might be a little bit like me but more of you well I hope that as he grew
What if she would maybe look like you so beautiful that I’d have two
Well they’ll grow slower than the wind blows
But faster as each day goes by
And when they're old enough to run they'll walk away one day
And I would have you back
Until then I can share - I’ll wait for when there's time to spare
But it always goes too fast
You should be the first to know that all I need is you and you alone
Well I guess that probably if I knew then
I'd finally understand when
Because “I told you so” became a reason
To know is too imposing
And life is what’s been chosen - but not by you and me
And so then - we watch them come and go and
Quietly they grow into someone just like you
And I know that I can only say so
Many times that I won't ever let you down until I show you
And when they're old enough to run they'll walk away one day
And I would have you back
Until then I can share - I’ll wait for when there's time to spare
But it always goes too fast
And every time they run past me and straight to you I understand cause I would too
But you should be the first to know that all I need is you and you alone
