Guardianship: How to End Guardianship of Your Children by Their Grandparents

My question involves a person located in the state of: Indiana

So my mother took my husband and I to court for guardianship of our kids while we were trying to get our house and job set up in Florida. She knew where we were bc we were sending her money. She deceptively some how got guardianship without us knowing. It's taken us quite some time to not only move back up north but get jobs and house. AND we just hired a lawyer. NOW we know the kids are miserable and just want to live with us. She already gave us our 11yr old bc she apparently couldn't handle him. Well when she found out we got a lawyer she not only took him back but said she was not allowed to speak to us or let any of our kids see us.(there is no legal bases that we know of for her to say that) I think it has scared her bc of all the deception she did to get the kids in the first place. What I need to know is if she is willing to give us back the kids right away are they allowed to stay at our​ house til the court proceedings?
