L.S.
don't talk about the baby so much. Spend time with her now and when the baby is born, but don't tell her you won't be able to do such and such when the baby is born or spend as much time with her. If you do, she will start to resent the baby now. Just let things go on as normal as possible. She is probably already getting anxious because you are talking about the new baby... and telling her, I won't be able to spend as much time with you. She doesn't understand that kind of talk. Just talk about how great a big sister she is going to be and how much she is going to be able to help the new baby. Call the new baby "our baby," not mommy's new baby. "The family is getting a new baby." She is getting a new little sister or brother to grow up with and play with and help take care of. Say, I'm so excited for you to get a new baby sister/brother to play with. etc. Buy her a special toy that she can give the baby. Buy a special toy for her that she can use with the baby. A special wash cloth, baby brush, etc. Buy her a toy from the new baby. Try not to talk about the new baby so much. :) Although it is hard not too. Hope this helps. My son had a new baby sister at 2 and half years old. Also, someone once told me, the baby isn't going to remember all the times you held her when she was first born, but your daughter will. (It doesn't mean ignore your new baby, but to not forget that your 4 year old will remember how much you hold your new baby). Hope that makes sense. ;)
