Some of this info may help you form a plan to get her into the cot (I don't think PUPD is indicated):
from:
Regaining Trust of Your ChildCrib Phobia up to 8 months:
(for children older using PUPD is suggested)
1) You must be patient and understanding. Never rush this process. This phobia may have been because of a tramatic event and forcing your child to do anything they don't want to right now will just make the situation worse.
2) Always comfort when your child starts to cry. Do not let them cry alone. Attend to their needs as soon as possible.
3) Start with the first nap of the day. At the first sleepiness cue start your wind-down. Swaddle and Shh Pat your child and when they are calm instead of putting them in the crib put them on a pillow on your lap. Tracy suggests a firm standard size pillow. Sit this your back against a wall for support. Let your child know you are there and will be there to help them sleep. When they have fallen asleep (20 minutes atleast) uncross your legs and let the pillow plop slowly and carefully on to the floor. Stay sitting next to the pillow. For the next week atleast stay next to your child while she sleeps. This is a sacrifice that you make to regain your child's trust.
4) The second week do the same wind-down but put the pillow on the floor for your child to fall asleep on, not your lap. Again stay with your child while they sleep through naps and nights.
5) The third week do the same wind-down but put the pillow in the crib. When you lay your child down put your hand on them so they know you are still there. For 3 days stay by their side until they are in deep sleep. On the fourth day remove your hand while staying beside the crib while your child is sleeping. Three days later leave the room when your child has gone into deep sleep but if they cry for you go to them IMMEDIATELY.
6) The fourth week you should be able to put your child down in the crib without the pillow. If not, start again from the previous step.
Tracy warns that this kind of phobia may produce a clingy child and restoring faith in your child now will help prevent this.
