In order to appeal, you will have to file a notice of appeal with the trial court within 30 days of the entry of the order. Here's a link to the rule: http://www.tsc.state.tn.us/rules/rules-appellate-procedure/4
Once the notice of appeal is filed, the case will be sent to the appellate court for review. The appellate court will issue a scheduling order that outlines the briefing deadlines for both parties.
The brief will contain your argument as to why the trial court's decision was not in the best interest of the child and that it should be overruled. The brief outlines the facts and the law that applies to your case. Then, the appeals court will rule on the matter.
However, the first step is to file your notice of appeal. You should see an attorney ASAP about getting your notice filed.
