Doubts About Sprouts

You're fairly close on the rhythm, but let me make a few suggestions: What? We're having beanie sprouts? / I have some teeny doubts.

As for the ending, perhaps:
With all these doubts, you know / just let the poor things grow.

or

Why hurt the tender shoots? / Just let them keep their roots.

or

...so many doubts about / those teeny beanie sprouts.
