R., I feel your frustration! I went through the SAME thing with my son AND daughter. The fact is, it is time to move her to a regular bed. If, and when, a child can easily climb out of their crib, for their own saftey, it is time to remove them from it and put them in their "BIG girl/boy" bed.
If I can offer some options for the switch -
Depending on the style of the crib, being convertable, and you want to use it for her toddler bed, you have to make the switch right away. If you are opting for a separate bed, being it toddler or a twin size mattress, keep the crib in her room, and set up the "BIG GIRL" bed on the oposite side of the room (you do not want to have the two seperate beds close together).
Take her shopping! Go look for toddler/twin size sheet sets that she would like. Get her involved! It could be fun! And it may also help with your anxiety through this process. :)
Have a talk with your daughter and explain to her that it is time for her to be a "big girl" now, and make the switch. Offer her the option of sleeping in her crib. If she trys to climb out of it, pick her up and tell her she must than sleep in the "big Girl" bed. She will possibly cry, whine, throw a temper tantrum (the change can be difficult), or, you MAY be surprised and watch her be very excited! She may want to sleep in her bed.
The next step, she will probably not stay in the bed all of the time. You would than have to explain to her that she needs to stay in her bed, just like YOU do. When it is bed time/nap time, you tuck her in, sing to her, etc. and say goodnight. It will not be easy! (That wole process of keeping her in her bed is another thing you have to conquer)
But it certainly sounds like the transformation NEEDS to happen.
And when you feel it is the right time, take down the crib, and remove it from her room, out of sight FOREVER. LOL
Again, this is ONLY my opinion. I did these steps and it worked for my children.
I do hope that my advise has been helpful!
And i do hope that other Mothers will respond to you as well, for listening to diffrent options is always a plus!
And, I would also speak to your pediatrician, just so that you could hear from an expert, someone you trust with the well fare of your child, and hear what they may have to say.
Good Luck!
