My mother requested this book from the library in Middenmeer for me, and my father brought it to the States when he was here for a month long visit.
It is a very nicely written book on the current knowledge on dual language children. It refers to modern research but also has a lot of practical examples and ideas. The suggestions are straightforward: be consistent, one parent one language, and make sure there's enough 'supply' of each language for the child.
The book describes that there are often two challenging periods: during the 3th or 4th year when the child realizes for the first times that it's speaking a different language at home then at school, and during puberty. Obviously, the 'problem' during puberty is less significant as by that age it is very unlikely for the child to forget the language.
It's encouraging to read again that children have no trouble at all learning an extra language or two, provided that the encouragement and language supply is there. Sometimes I worry a little about Nora -- will she have a hard time starting school because she doesn't know English yet? -- but the book reinforces that kids will have no problem quickly learning the main language, and that in fact the biggest challenge will be to maintain their minority languages.
In addition to general information on dual language acquisition, the book describes foreign language education and multilingual schools in the Netherlands, which was interesting to read also.
Well written, recommended.
