I think a post like this is more than welcome and fits within the scope of this thread. I rejoice with you that she has begun her journey back.
Later in life, when I told people that I was raised Christian, they would ask me what denomination. I would look at them kind of funny and tell them "Christian?!". At first, I felt a little inadequate because it didn't seem my answer was enough. After a while, I caught on and learned the term non-denominational. But growing up, I was just Christian.
