D..
She's already used to it, tired mommy! She found out SO quickly that you would hold her, and now she's holding you to it!
So sorry. You are going to have to tell her night-night and let her cry. If you will just soldier on for a week without picking her up at all, not talking to her, it will take about a week.
Let her cry for 5 minutes, then go in, pat her on the back, and leave for 10 minutes. Then go back in after 15, then 20, etc. Add 5 minutes. You HAVE to watch the clock. She will finally fall asleep.
If you can't do that, you could sit on the floor beside her crib and just touch her leg through the crib slats. She will know you are there but you aren't doing ANYTHING else. That will wean her from being held, and you are there for her til she gets back into the sleep mode. Then stop sitting in the floor and let her whine herself to sleep.
If you decide to do this, don't vary one iota. If you cave in and pick her up, you will undo everything you've tried before and she will cry twice as hard because she knows that crying gets her what she wants - a night time pass with mommy. Very tired mommy!
You can do it! And you'll both be happier in the long run!
