I was an only child so this concept is all new to me!

E said something very perceptive today. She said "baby sister cant have my toys". I said she will need to share because its more fun playing together, blah blah. But it got me to thinking..... how does this work? E has a lot of toys but also a LOT of books and they are all "hers". They live in her bedroom. I was just presuming they would share the books and also the toys once #2 is big enough, but is that realistic?

I also have a box of baby books I purged from E's collection before Christmas. Is she going to wig out when she sees her books in the baby's room? Do I help her to deal with it, or will it cause too much resentment and suspicion?

Ideas and advice welcome! How did it pan out for you? Did you do anything special to ease the transition?
