Once TPR happens, how long does it take to adopt?

Hi all I'm in FL and my kids were TPR'd last Dec 16th. The birth father filed an exstention and didn't end up filing his appeal until August. I was floored that this is exceptable, i could understand if he has remained in contact with the children or even worked on his plan but he has not. He hasn't even seen the kids in 2 years and 9 months. The birth mother signed over her rights last October on my Daughters 6th birthday and that is when they were placed with us. Are next court date is Nov 17th and it is a status hearing. SO good luck it may be a long bump road ,but boy is it worth it!:)
