How long after a placement hearing until the children are placed in a relative's care?

( I posted this in Law and Ethics too, cause not sure which would be best.)

My cousin had her kids back for two months, then CPS took them again. The 60 day hearing is coming soon and there have been 2 home studies done on family members. If the Judge chooses to place the children out of foster care and into a relative's home, what is the expected time for that to happen? We know our home study was positive and it sure would be wonderful to have the children placed the same day as the hearing. We cared for them (CPS placement) half of last year, haven't seem them in two months, and miss them. Just wondering what to possibly expect with all this.
