My brother moved to England with his family from Spain two years ago. He is English, but bilingual, his wife is Spanish and speaks OK but not brilliant English. They have two children, dn, who went into year 4 and who now speaks excellent, but quite heavily accented English, but who is obviously doing fine, as she has just passed the 11+. My concern is for my nephew, who was 5 when they moved. He was a late talker in any language, and his English is still no more than adequate. I thought this was because he spoke Spanish at home (they do still keep a very "Spanish" way of life as far as they can - late lunch, late bed times and so on) However, they recently had visitors from Spain, and it turns out that he can barely speak Spanish any more although he understands it. I am very concerned that there doesn't seem to be any language that he can speak perfectly. His parents just think that it will come, but it doesn't seem to me to be right that he can't express himself fully in either language. Is this a common occurence, and can people reassure me that he will, sooner or later, end up completely bilingual and I'm worrying about nothing?
