Multi lingual child - how to keep up French
My son is 3.5 now and spend his first 3 years at a FR speaking crèche in BXL. In September he started at a Flemish local school as this is one of his home languages (other is Spanish). While his Dutch and Spanish are improving, I would really like to keep the FR also ´alive´. He therefore goes to FR sports classes once a week. However, the teacher there says she feels he doesn´t understand all the instructions. How can I help him? I can of course read books to him in FR but worry that as a non-native speaker, I will do more harm than good (My FR is reasonable/ok, but not at native spaker level). At school FR classes will only start when he is 7. Any advice is welcome!
