"It does not matter if we do not have children."

Translation: Não importa se não temos filhos.

[chogu]

Criancas?

[Nonzo]

Am I correct in understanding that 'se' here is not a pronoun at all but simply the word 'if'?

[Paulenrique]

Yes.

[KemotS]

Does "Não faz mal se não temos filhos" have the same meaning ?

[Paulenrique]

Yes =)

[Nonzo]

Obrigado.

[Dr.Fandey]

Não faz mal?

[hemiraclelamb]

Mesmo, why is "não faz mal" wrong?

[JCMcGee]

Bad translation.

Filhos suggests "our own children"

[Friznutz]

Why is crianças not accepted here?

[ThePope78705]

Why is meninos not accepted?

[Florian823137]

"Meninos" means "boys", but not as family members. If you want to say "boys" as "sons" you have to say "filhos".

[roizhems]

Why is E nao... not accepted?
