Two-year-olds are unlikely to understand the concept of a new baby as they are just starting to understand their place in the world. However, it's great you're thinking in terms of how to make the transition to having a new baby a smooth one. I'd wait until the time gets closer before trying again. There are plenty of great new baby books to read to little ones. This would be a good place to begin. Also, if you have any friends with new babies, invite them over. Pull out baby pictures and talk about your two-year-old when she was a new baby. Some hospitals have new sibling preparation classes. These are terrific programs. Don't worry about your little one not understanding. She'll catch on once you bring the baby home. Although some little ones show about as much interest in a new baby as they would in a new couch. To foster positive experiences with the baby, give her plenty of opportunity to be involved: let her touch the baby, push the stroller and choose clothing. Be careful not to overdo talk about the new baby. Good luck, Cathryn Tobin, M.D.
