My daughter filed her tax return and claimed her baby boy as a dependent, which meant she also claimed herself. Can I claim her, since she lived with me for 7 mons?

My daughter lived with me for 7 months, before moving out on her own.  According to the questions that Turbo Tax asks me, I can claim her as a dependent. However, since she claimed herself on her own return, I'm guessing that I cannot claim her, too.
