(((Lisa))) - I'm glad your niece is doing so well!!!
As far as your sister...give it time. She still has 92 days to get through and with her past record....well, we'll see. I'm not wishing bad things on her, but I have to admit I am skeptical.
Just keep your focus on you and your niece. Your sister is great at "talking the talk"...let's see how she does at "walking the walk" now.
Hugs and prayers!
Amy
