We purchased a lot years ago and have a baby in the grave.  I go over and put flowers on her grave as I feel that is the least I can do for her.  They keep the grave site up and if there is a problem, they take care of it.  I did have them last year raise up stone as it was sinking down.   It has been in the ground since 1965, so I guess that is a normal thing.  However, they raised it up to my satisfaction.  They have good caretakers over there.
