Hi L., how about assembling pictures of the 8 y/o and 2 y/o together starting w/ when the baby was born. Show them together playing, reading a story, eating birthday cake, Christmas, washing dishes, trying on new shoes, fixing hair. Any and everything that the older girl will be doing on a regular basis. Tell your child that Morgan will be doing all those same things and when Vivian is doing those things she can see the pics of her and sister doing it together. It may bring comfort to the older child to have those same pics. Perhaps you could make 2 simple albums the same and have the girls give them to each other so they will still be together for the time they are apart. Leave enough room in the album for pics to be mailed of Morgan at her new school, if she gets a new hairstyle, or does something (skiing, mountain climbing)that Vivian would have no frame of reference for. Likewise as Vivian learns to ride a bike or hop on one foot, send a pic of that to Morgan to see her sisters growth. That way they will never be apart. HTH
