Foster System Question Florida

First time Foster parent in Broward County (Ft Lauderdale) Florida, and I need help in understanding. We have had a foster child with us for 18 months and the mother has done all she needed to do but still can not be unsupervised with the child. A week ago they changed the Judical Review Case plan to Adoption. What does that really mean? What are the next steps? we really want to adopt this child, its the reason we became foster parents, but what are courts steps and what can we expect to happen and maybe a possible time line? Can anyone tell us how this system works, or supposed to work? Next court date is three months with the magistrate. I appreciate any help or information and type slow because I really need this broken down. Thank you.
