My 4yo (I know...) has a dummy for sleeping at night. We've tried giving up before for about a week when she was 3, and she did manage to go to sleep but it took til 11pm each night and it was so difficult (I was pregnant and shattered) that in the end I let her have one back.
Now we've managed to get to the point where she just has it for about 10 minutes to get to sleep then I take it out of her mouth and she manages the night without.
The issue is if she doesn't have it she gets almost hysterical at bedtime. She can't relax, gets totally hyper, can't stop talking and making noises and twirling round on her bed, getting up etc. I can't get her to be still so she can get off to sleep. Tried breathing techniques, body scanning, about a million stories, "hypnotic" stories (totally bloody useless). And she fully believes she can't go to sleep without it so gets quite anxious - i can't see it getting any easier by leaving it.
Any ideas? Shes desperate to give it up incidentally. Don't need techniques to persuade her which is all I can find online - it's just how to I get her to sleep?! Thanks x
