The song tells the story of a mother (nanay) and a father (tatay) caring for a new child. Here is an approximation:
Si Nanay and Si Tatay
Working hand in hand today
Bringing up their newest child
In their hearts, pure love compiled
From morning's break until the light starts to fade
Their caring presence never sways, never strays
Si Nanay's lullabies echo sweetly and true
To comfort the babe until slumber ensues
Si Tatay plays, laughter spreads with each chime
Bringing joy to those precious moments of time
As the sun sets, with soft and tender care
They gently hush a drowsy head nestled there
Together raising this dear one they hold
Si Nanay, Si Tatay a story well told
Through simple acts and love in unity bound
A family formed in harmony profound
