Yes, but you'll have to do a massive rewrite anyway to change from telling to showing. To learn how, besides looking at Emma Darwin's tool kit, you could check out other children's writers' posts on here and the feedback they got.
As far as POV, I currently have two in my book and I've just been advised by Townhouse to remove one. (I've just posted for feedback too!) There are several examples of chapter books that do have two POV, so you may decide you need two. However, you have large amounts of text where it's unclear as to whose POV you are using. Like the first 3 paragraphs to your story:
Another day was ending over Buttenhauser's meadow. As the sun set, the forest creatures of both the night and day gathered at the old story tree to watch the full moon rise. Full-moon nights were always exciting because that's when Grandpa Owl would a new story from his book of twilight tales.
Silvery rays of light fell onto the thick branches of the old tree as Grandpa Owl emerged from his nest. Carrying the big book of stories in his giant gray-feathered wings, he perched on his favorite branch. Everyone grew quiet, wondering what tonight’s story could be.
The sound of wildly flapping wings filled the air. "Look out", cried Nelly. "Nosedive is coming!" The little squirrel scampered to the ground in a flash of red-brown fur. Nosedive's arrival always caused alarm. Because although the young bat could fly, landing was still a problem.
Who is doing the thinking here? The owl?
If the below text is from Belfry's POV, you need to show it all through his eyes. How does Belfry know his parents are worried? Or that Nosedive's friends are feeling guilty? You can show this through dialog or actions, but you can't tell us what others are thinking because Belfry wouldn't know, he can only guess.
The next morning at dawn, Nosedive's family returned to their cave. Since they hadn't seen him all night, his parents worried when they didn't find Nosedive at home. Belfry didn't worry at all. He was sure that his annoying little brother was still out practice-landing; wearing that silly helmet.
It was getting late. The sun was already peeking over the horizon and Nosedive still wasn't home. Now Belfry started worrying too. The family went out to alert everyone in the meadow that Nosedive was missing.
Feeling guilty for having left him alone, Ellis, Nelly and Hopper promised to look for their friend until nightfall, when the bats could take over searching along with Ollie. All the other animals helped look for Nosedive too - even Red. Nosedive's mother worried that her son wouldn't find a safe place to sleep.
I hope this makes sense, I'm new to critiquing so forgive me if I'm too blunt. Good luck with your rewrite!
