Millie Martin died on Friday evening at the Royal Victoria Hospital in Belfast, following an attack at a house in Glebe Park in the Co Fermanagh town.
In a statement released to UTV, the family said: "We are deeply heartbroken by the death of our beautiful little Millie.
"The entire close-knit family are numb with pain - we simply can't believe that our loving, darling little angel is gone."
The family said no words could describe the distress that they are going through.
"Millie was our beautiful and precious little girl and we feel blessed to have been able to share that short life. She lit up our lives and brought us endless joy."
The grieving family have also asked for their privacy to be respected "at this distressing time".
Detectives have been handed an extra 36 hours to question a 30-year-old man about the murder of the baby girl.
But investigators have refused to disclose the results of post-mortem tests on her body.
A PSNI spokeswoman said they were being withheld for operational reasons.
The house at Glebe Park, off the Old Tempo Road, in the Chanterhill area of Enniskillen remains sealed off for technical examination by forensic experts.
The child was first admitted to the Erne Hospital in Enniskillen on Thursday night before being transferred to Belfast.
She died in intensive care at the Royal Victoria Hospital.
Western Health Trust staff are assisting police.
Glebe Park is a residential area of the Co Fermanagh lakeside town on the road to Tempo.
