To be able to: Usos naturais

Hi!

I'd like to know if the sentences below sound natural to a native speaker. Could you help me?

"My daughter has been able to read since she was 4."
"I've been able to play the piano since I was 10."
"My son has been able to write since he was 5."

Thanks in advance!

Yes, they're natural, idiomatic sentences.

''My son is 2 1/2 years old, and has been able to read since the age of 2.'' [Yahoo - Voices - USA]

Bons estudos!
Thank you so much, Donay!
