we've just (6 weeks ago) moved back from Spain. ds1 and dd were fluent in spanish but seem to be losing it fast: we have a spanish time every day (well, most days) and it's very hard work making them speak it, and when they do they seem to have forgotten a lot. they watch dvds in spanish twice a week too.
I'm going to try to find a native speaker who can pretend not to know english, but it's going to be hard as we're in the sticks. has anyone got any other ideas?
