My 11 year old feels that way about my new husband. I try my best to give them both equal attention and it's hard. She is excited to have a baby sister almost here though. All I can say is always include your daughter in all the plans for the new baby and try to do some special things she likes to do with her. You don't need to spend money or take her somewhere all the time, she just wants to know and see you love her and want to spend time with her too. Good luck to all of you.
