Anyone who has done gradual withdrawal with a toddler (camping out in their room) and had success stories?

[Babyisaac]

DS is 2.4 and for the last 8 weeks he has been getting out of bed up to 4 times a night. He went into a bed about a week before this started happening.

We have been using the Supernanny approach of putting him back each time he gets up and avoiding eye contact, talking etc. The thing is, I don't think we're getting anywhere at all. The only way he stays in bed eventually (after going backwards and forwards about 30 times) is through sheer exhaustion. I honestly don't think he's getting any sort of message.

The problem is, he's completely hysterical and will not entertain the fact that it is nighttime and he has to stay in bed. He just wants his mummy or daddy to stay with him. He has a Gro Clock but, although he knows what it means when you talk about it during the day, couldn't care less about it at 2 in the morning! We have discussed rewards etc but the same thing - couldn't care less, just wants us to be with him.

Should I persevere or do you think I should go back to basics and teach him to be able to sleep by himself again? If so, how would I go about doing this?

Any views welcome!!

I would say persevere but after eight weeks, maybe you need more help. I tried this pre-Supernanny and it worked after just a few nights - however, we had been recommended a book, can't remember the title now, and the book said that BOTH parents had to read it, DP didn't to start with but it was only after he had also read the book that the technique began to work.
I suggest finding a book on the technique so you can be sure you are both doing it right.

DD was older, but we went through Millpond Sleep Clinic recommended by anotehr MN'er. I do know they do a book aswell.
