A baby's gotta do what a baby's gotta do

I look back and there
Is a determined and wet
Toddler toddling
As fast as she gets

Her raincoat is soaking
And stuck to her clothes
And her wellies are sloshing
Around her small toes

Her mouth is set
In a firm, straight line
And her hands are clenched
And she's keeping time

I can tell just by looking
She's miserably cold
But she keeps right on walking
Because she does what she's told
