(NEWS CENTER) -- Trista Reynolds says someone knows something about what happened to her daughter, and that person needs to come forward.
Reynolds' daughter, Ayla, has been missing since December. She was 21 months old at the time.
Since then, police have sifted through hundreds of leads, and say Ayla did meet with foul play. Her blood was found in the home of her father, Justin DiPietro. That home is also the place she was last seen.
Police also say DiPietro has not told them everything they know.
But police continue to hold out hope that Ayla is alive, as does Reynolds.
Reynolds said she starts every day with the same thought: Please let this be the day that Ayla comes home.
Reynolds said, "I can't wait to see her running to me and just arms right open. And just 'Mommy! Mommy!' And hearing everything that she's got to say. I picture a lot to keep me going."
Reynolds said she's running on hope, and the fact her 9-month old, Raymond, needs his mom, too. Reynolds doesn't let herself think that Raymond's big sister is hurt -- or worse. She doesn't let herself think about the blood found in DiPietro's home. "I can't," Reynolds said. "I just cannot think about it, or think about why it's there. There could be many reasons. There's no one to blame right now because no one knows. I'm still trying to comprehend it right now."
Reynolds also said she's not pushing DiPietro for answers. She's letting the police do that. "Maine State Police have it in their hands," she said. "I will not question, I will not blame, and I will not point fingers." In fact, Reynolds and DiPietro seemed friendly at a vigil for Ayla this weekend.
Reynolds said, "I don't understand what the big deal is, why everybody is making such a big deal about Justin and I being at Ayla's balloon event and supoprting her as Mom and Dad. We are friends. We've been friends. We just don't see eye to eye sometimes. But what parent doesn't? But we're still Mommy and Daddy to her. And we were supporting Ayla together."
"He is the only one who knows what I'm going through. He's going through the same exact thing that I'm going through, missing his daughter. We're missing our daughter right now. If it's anybody who knows, he knows that I'm going through on the inside every single day."
But Reynolds is furious that someone out there knows where Ayla is, and hasn't come forward.
"How do you sleep at night? How do you eat? How do you go on, knowing up here that you've done something so wrong. How do you just -- How do you find it to be OK?" she said.
Reynolds says she continues to do interviews and appear at public events because she doesn't want anyone to forget about Ayla. She can't stop thinking about her. "How big she's gotten. How long is her hair? How many teeth has she got? How many words has she learned right now?"
Reynolds knows one day police may tell her the worst news a parent can hear. But until then, she has hope. Someone's conscience will get the better of them. And then... "Ayla and I will be reunited. She will. She's coming home to me."
