Separation anxiety and labor

I am currently pregnant with baby #2 who is due in early August. My daughter is almost 8 months old now but will be 1 and 2 months when this baby arrives. As of right now she has severe separation anxiety. She screams the entire time I am out of her sight (even with my husband) and is completely inconsolable until I come back. I know I still have a while until I will be in labor but I’m trying to start preparing her early for my overnight or few night stay at the hospital. What are some things I can do with her to help her? The thought of her crying and I am unable to help just kills me. She may be over her anxiety before the time comes but I’m not taking my chances.
