Casey Anthony has blown off another visit with her family.

The 22-year-old mom of missing toddler Caylee Anthony was supposed to see her parents Sunday night but declined.

"I'd like to see her, but what am I going to say?" asked Casey's mom, Cindy. "If she wants to not see us, that's her prerogative."

This canceled visit comes after Casey refused to see her brother, Lee, last week.

Cindy also says that her daughter might be refusing family visits because she canceled a visit with her last week in order to focus on finding Caylee.

Casey's family has also made some critical comments about her recently, and that may be playing into the young mom's refusal to see them.

"She has to pay for some of the stuff that's she's putting herself through and what she's put her daughter through," said Casey's dad, George, last week.

But Casey's family isn't giving up on her. They've rescheduled visits for this week, and her brother, Lee, says he still believes she's telling the truth to the best of her ability.
