Yes, absolutely. I think you should go with your gut. I was only speaking generally and not specifically about your piece.
I just wanted to point out that if you aren't rhyming, you might want to consider going with free verse. Lots of great examples of free verse in children's books.
I clicked to read your poem and the lack of rhyming seems to fit the tone, actually. And it does read more like free verse. It has a lovely, lyrical quality!
