We teach this little critter some of our common Catholic language - Latin - all the time! When she wants to give a shout to the Lord, she says: Laus Deo (Praise God)! When she meets the enemies of the Church, she exclaims: Papa sit Rex Romae (the Pope shalt be the King of Rome)!
She's learning some Aramaic, too, the language that Christ spoke while on earth (thanks to our local Lebanese Maronite parish!). Old Slavonic and Hebrew are in the works along with some classical Greek, too!
