had the same thing! We had to transistion from our bed to her cot and get her into a regular bedtime routine. Just like PacRakMG we converted her cot to a toddler bed (we put a rail up just in case), she thought it was just great, but first we had to get her into a bedtime routine. We started putting her down at the same time every night, and yes she screamed and cried and sobbed. But we stayed with her, patted her, cuddled her until she went to sleep. Sometimes took 5 minutes, other times an hour. When she got used to that, we would put her to bed (in our bed still) and say goodnight and walk out, so she could get used to going to sleep by herself. Then we converted her cot over to a bed, and I asked her one night if she wanted to sleep in her big girl bed or mummy's bed and she chose her bed, and goes to sleep there very easily. Yes she still comes into our bed at some stage during the night (usually anywhere between 2.30 and 6.30), but we can live with that for the moment. She even now goes to her bed for her nap during the day when she had to sleep on the couch with me before. It took about 2 weeks to get her into her own bed but it was well worth it.

Good luck!
