I confess that I put these out there because these are so creative. My husband lived with a German family when he was attending a German language school in the late 1960s. Here it is nearly 50 years later, and he still remembers a lot.
Our oldest grandson (8 yrs) in Switzerland has announced that he speaks four languages: British English, American English, German, and Swiss German. Dang, he does!In 30+ years ago, when we lived in Ireland, our children learned English and Irish Gaelic. Our oldest was 10 yrs. old, and wasn't required to learn the Irish. Our son was in 2nd grade and daughter was in Jr. Infants (young Kgt) He became quite fluent, so much so that his teacher wanted him to skip a year.
