Hi Murchik, glad to hear you're enjoying your Little Reader free trial so far! Unfortunately we don't have a Spanish curriculum for Little Reader just yet -- this is something that we just started working on, and we cannot provide a specific release date for now.
In the meantime, you can create your own lessons in LR (for any topic or language you want to teach), as many users have been doing. You may also download Spanish LR files from the downloads library which you can quickly import into LR. You may check out the Little Reader Foreign Language Downloads here:
