I always make sure to tell them I love them every night. I know they don't know what it means, but I secretly hope they do. I actually didn't realize how much they meant to me until one got an infection. She wasn't even my favorite girl. She actually really doesn't have much of a .personality at all, but once I found out she was sick, I was just as worried and motherly to her than if it was anyone else In my life. I was crying and spending all this money and researching non-stop. I would have done anything to help her. I think I even prayed. She is good now!
