The latest message, posted to mark the 11-week anniversary of April's abduction from near her home in Machynlleth, Mid Wales, suggests relatives are continuing to hope for a miracle.
Searchers are due to take a two-week break from the hunt for April's body but will be back in force in the new year.
Superintendent Ian John, of Dyfed Powys Police, who is heading the search, has paid tribute to the family's "great dignity and resilience" and spoke of their strength of character.
He also read out a message from April's parents in which they describe "coming to terms with the fact that our baby girl has been taken from us".
The latest Facebook message reads: "11 weeks now my baby April been missing... we just want you home for Christmas.
"It's so hard you not here running around asking how long before Father Christmas is coming and you trying to open your present and try and help us wrap presents for family and friends . . . please come home."
The schoolgirl was last seen playing out on her bike close to her home on Bryn-y-Gog estate in Machynlleth on the evening of October 1.
Mark Bridger (46) has been charged with April's murder. He is due to appear at Caernarfon Crown Court on January 11.
