My 5 year old daughter is being taught French in school and she hardly remembers anything. Does it make sense to teach foreign language if the parent doesn't know the language?

Yes I think learning a foreign language even if the parents don't know it is good. But some kids just don't have a flair for languages and perhaps prefer certain languages so I think it is better that they have a choice in what foreign languages they want to learn or do they even need to learn it. It is right to say kids have the ability to learn multiple languages when they are young but I read somewhere before that we should only introduce a foreign language after they have established the foundation for their main languages
