On a practical note if he has a memory for languages (however he is exposed to them or even if in some mystical way they are innate) and if it may have a window of opportunity that could close/fade (as TX G experienced) I think you would try to find him someone to talk with in that language as much as possible. (or multiple languages).

When my SIL wanted her children to "keep" their foreign language, after moving to the US from abroad, she had a tutor make crafts, play games, etc with them --in the foreign language.
