Vba2c or vbac?

Yvonne
Has anyone had a vbac after 2 c sections. My kids are 11 and 7 (will be almost 12 and 8) when I deliver. 1st section was an emergency, 2nd was no vbac hospital policy. 
I don't see my ob for a couple weeks and if he says it's safe, I'd like to attempt a vbac. 
Thoughts. Has anyone been successful? Especially after 2.
