D..
Don't give her back the paci. Don't rock her. Don't change her diaper. Don't take her to big bed. Give her the giraffe, the night lights and leave the door open.
You really have to let her get past this. If you waver, you'll have more issues with bedtime. If you stand firm and tell her it's time for bed and walk out, and don't go back in, then she will learn. If she gets out of bed, walk her back without a word. Over and over. Don't give in.
Good luck,
Dawn
