S.L.
I went threw the same thing with my daughter, what seem to help us was i wore a shirt and put my perfume on it, i would give it to her all the time so she could smell my scent and know that i was close. i also use to call and check on her quit a bit, (which im sure you do as well.) you could even have her pick the shirt out for you to wear and her to keep with her. i hope this helps in some way for you, let me know how it turns out or if it even helps for you.
