Both DH and I are English, living permanently in Zürich. Obv speak English at home and with friends. DD is 8m and goes 3.5 days a week to a bilingual English / German nursery, which is if anything heavy on the Swiss German, with occasional activities in English.
Do I need to do anything in particular for her to be properly bilingual when she starts to talk or will it just be natural? Any tips or good books on the subject? Don't want to be pushy mother but would like to encourage her to read etc.
