My daughter was only 24 months when I had my son. Try and have her help with the baby. Like when you go to change him, have your daughter get the wipes and diaper for you. If you are bottle feeding let her help. I sat right next to my daughter, put her arm on some pillows to raise his head, and let her feed him. I watched her very carefully, and she did a wonderful job. This allowed her to get use to her new brother, and mommy was sitting right next to her. Sometimes I would grab a book and read it to her while she was feeding him. Try and get her involved with the baby. She might just feel like she is being left out. I couldn't tell you. I would say let her hold onto the paci for right now and see what happens after you try getting her involved with him. Hopefully she will forget about it, and you can go back to her using it at bed time and nap time. Hopefully that will help. Take care and let me know if you need any more suggestions.
