Replay your child's babyhood. Get out the photo album from your older child's baby days and show and talk about what she looked like. Show her pictures of how she was nursed and carried in your arms. Talk about the presents she got when she was a baby and the visitors that came to meet her. Talking about the older sibling's baby days prepares her for what babies are like and reminds her that she, too, got a lot of attention when she was tiny.
Some hospitals even have classes for expectant siblings.
Include gifts for your older child. Since your friends will lavish gifts on the new baby, the older child may feel left out. Before you go to the hospital, wrap several gifts for your older child and stash them away for when people come to visit the new baby. Your child is probably worried that she won't have enough time with you, and she probably won't. It's unrealistic to think you will be able to give 200 percent.
