Child-Proof

There’s a child-proof cap

That’s beyond my strength,

Though I’ve tried my best

To get it off, at length.

First I push, then twist 

But it’s staying stuck 

And my grandson would

Thus be out of luck

But his dad will soon

Be back home and then

There’ll be medicine

‘Til the next time when

His new dose is due;

Then there’ll be no goof 

For a dad can open

What’s Nana-proof.
