George and Cindy Anthony, were overwhelmed with gifts over the weekend from people throughout the nation for the child's third birthday.

"This is a tough day for us today," Caylee's grandfather George Anthony said. "And if you guys have children or you are grandparents, you are going to understand (that) these days like this don't come around very often and when they do, they mean more than anything."

Families traveled to the Anthony home to deliver birthday gifts.

"It is important for them to have that hope," neighbor Samantha Gaglioti said. "That wherever she is, that she is being treated well and having someone saying happy birthday to her."

"I can't imagine what this family is going through," resident Lisa Smith said. "We met them at the vigil and my heart goes out to all of them."

George Anthony held a picture and T-shirt sent from a family in New York.

"It is people like this that give us the strength to keep going," George Anthony said. "And I'd like to say, Mrs. Schultz, if you are watching this or your family or anyone else out there who is sending us things, know that we are getting them and I appreciate these more than you can imagine."

A volunteer said she has neglected her family to find Caylee.

"It has been a lot," family friend Holly Gagne said. "I haven't made a home-cooked meal in three weeks. I haven't put my kids to bed. Right now, they understand this is where we need to be."

Case Makes International Headlines

Local 6's exclusive interview with Zenaida Gonzalez is now making international headlines in newspapers in Europe and South America.

Local 6 spoke with the only Zenaida Gonzalez to visit the Sawgrass Apartments where Casey Anthony said she left Caylee with a woman by the same name.

'Safe House' Considered

Baez also launched a new appeal to spring Casey Anthony out of jail.

However, with talks of threats against the family if Casey Anthony leaves jail, Cindy Anthony has considered the use of a safe house.

"Right here, I don't think is the ideal place for her not because we don't want her in the house and everything but we may have to hole her up somewhere in a safe house," Cindy Anthony said.

A national search for Caylee continues.
