While reading it, this poem had a tune in my head! It could be a very charming little song. :D It flows very nicely.
One thing though, in the final lines, I think the -ay sound shouldn't be used to end all three lines. But other than that, it's perfect. :)
Sorry, I'm not much of a poet myself, but I will tell you that this poem has a wonderful feel too it. The rhyming and flow are great and I don't thinking anything needs to be changed. The repetition of of wording works really well for me.
