"Ela cuidava de você."

Translation: She took care of you.

[YuMoises]

"She used to take care of you" it´s a correct answer.

[ZuMako8_Momo]

It is accepted

[emeyr]

Ela cuidava de você [quando você era bebê].

She took care of you [when you were a baby].
She used to take care of you [when you were a baby, but now she works for another family].

"Used to" can imply a contrast with the past while the "simple past" describes a past situation.

[IvanEb]

"She would take care of you."

Shouldn't this be accepted?

[Paulenrique]

Yes, it's also right.

[Kevin47007]

That would be "Ela cuidaria de voce"

[Paulenrique]

And also "Ele cuidava de você".

[GrannySlasher]

'Cuidar' is always followed by 'de'?

[Paulenrique]

Yes (when you have a complement).

[Kevin47007]

Much like English, no? You can say "Take care of yourself.", and you can say simply "Take care", but I'm not a native Portuguese speaker, so I won't pretend to know the best translation for "Take care".

[Ymeagain]

For some reason I entered 'She used to care for you' which was accepted also! Maybe this can mean 'She used to take care of you' but I thought this might be a different usage - closer 'to care about somebody' for which my dictionary suggests 'preocupar-se com'.

[ZuMako8_Momo]

Your dictionary is correct. It is interesting to see how, in English, "care for" can mean "take care of" or "care about;" it is one of those situations where the preposition can be ambiguous in the interpretation of its meaning.
