Hi renagr8,
Welcome to BrillKids
You do not have to apologize for the length of your post ever
It is so great to hear your son is enjoying exploring his surroundings. My Little Prince has started pulling himself up it is amazing he will come so close to your face and look you directly in your eyes with a look on his face like he is concerned for your well being and then he will break out the biggest smile ever.
I have been back and forth on the idea of teaching my son other languages before he is speaking our native language.
The only downside I have found about teaching him multi languages this early is that it may create a speech delay.
After I researched the delay average (it is not much at all until you start teaching more than 7 languages) I am continuing to teach him chinese and spanish and of course our native language English.
You can incorporate Greek into the Little Reader program by adding your own voice etc. please follow the link below to a recent post where Kezia gives complete instructions
