How do you say my only daughter in french?

Answer 1

I am not an only child is "je ne suis pas enfant unique" in French. Although this is correct, the way we would say it is "je ne suis pas fils unique" (only son) or "fille unique" (only daughter). Or we would say "j'ai un frère / une soeur" (I have a brother / a sister).

Answer 2

ma seule fille (I have only one daughter - but I may have a son) or ma fille unique (she is my only child)

Answer 3

seul enfant
