I think you may be qualify to to apply for ILE (Indefinite Leave to Enter)since the family live outside the uk for more than four years.

''We may be able to give you permission to live permanently in the UK as soon as you arrive, if:
you and your partner married or formed a civil partnership at least four years ago;
you have spent those four years living together outside the UK;
you are both coming to the UK to settle here together; and
you have sufficient knowledge of the English language and life in the UK. (You do not need to meet this last requirement if you are aged 65 or over.)''
..have you applied your daughter a british passport?
