Can anyone tell me if there is a meaning for this word?

It really sounds Russian or lithuanian or something in that area or it could be slovak. It sound familiar..

ah ah wait I found on google where Reiksa is used, It is Estonian definately I am sure but I do not know what it means.. but disregard what I wrote above the word is definatly estonian.

Also, If you spell it "Rieska" that is a Finnish word for a recipie made of rye bread.

Hope this info helps...Your son must be a genious! :)....seriously.

ur son made it up......before looking to see it in different languages, why didnt u just ask ur son where he learned that word?? he might've also seen that in a tv show as a name.

Your son is four years old.. he made it up or is trying to pronnounce another word.
