Thank you for your responses thus far. We are ideally looking for Russian or Spanish but given the limited availability, we'd consider anything (so thank you for the suggestion of the German nursery). We're currently living in Armenia and our nanny speaks Russian. We're with the Foreign Office so will always be in living abroad when not posted to London. Our daughter will be two when we return to London next March and we'll just be looking for a few mornings a week. Thank you again.
