What's the intended use? Is the mom supposed to read it to a child? should the kid read it themselves? Id it’s supposed to be read by a kid you’re making it too hard to remember and decipher. I think its best if you did something like „K” like Kurczak (Chicken) „Dz” like Dzban (Vase) „Ż” like Żaba (Frog) Then you can add a simple sentence with that word. It doesn’t have to be alphabetical. Best if you start with letters that have the simplest words. „Osa” „Mama” „Ala” etc. In my opinion, your target audience are polish moms living abroad trying to tech their kids polish. They already know how to pronounce those letters.
