DD will be around 2 years 3 months when baby sister arrives. She knows "baby's room" but I don't think she GETS it (obviously). I've been showing her the baby's clothes, diapers, etc...we have been putting newborn diapers on her dolls together, talking about how little, putting her doll in the baby swing etc.

I am so nervous about this. She is a total mama's girl and really takes awhile to warm up to other kids her age/younger so I have no idea what to expect.
