Ava -- whom Casey adopted two years ago -- has been living with Casey's mom, Sale, for the past few months. We're told it's the family that wants Ava to remain with Sale -- along with her husband Ahmad Rashad* -- for good.
Sources close to the family tell us Casey's sisters will also help out.
It is unclear when (or if) the Johnson family will file adoption papers.
(*Yes, the Ahmad Rashad)
