I didn't do EC with DS but read a book on it when DS was nearly 2.5yo, Natural Infant Hygiene by Ingrid Bauer, and in it she said that night continence is the easiest outcome to aim for. So, I took the plunge and went back to sleeping with DS. He had co-slept for more than two years and when he got his bed decided he would fall asleep in his new bed, coming into our bed later. For the night continence, I decided to stay in HIS bed with him, with a potty in the room and use the EC principles, which use knowledge of human elimination from physiology.
Within two weeks he knew what to do and I started to go back to my own bed. Initially he didn't like it, and we persisted till he was comfortable with it. He realised that I was there with him and I realised a lot of things in hindsight about windows of opportunity I had missed when he had been sleeping in our bed.
No tricks or anything, just ancient human infant knowledge and some fancy physiology intel to get night continence off the ground Highly recommend it, especially the extra snuggles
ETA:
One important thing: limiting liquids after a certain hour is NOT night continence, it's dehydration, and is not very healthy for them. True night continence is when they are properly hydrated (and DS was having a night feed to go to sleep, and then having a feed in the wee hours and staying in our bed, staying dry) and still able to manage their sphincters. What we do with nappying is train the baby out of their own awareness of their elimination. When we conventionally, then, toilet train we reteach them what they initially knew before we trained them out of their awareness. That hormone secretion for limiting urine production is always there, as are the sleep cycles. So, as with DS, I had to get him reconnected with his cycles so that he'd know what to do with the sensations. It's not easy, it's not quick, and it's so, so satisfying.
With DD I started at 2 weeks and she's been night continent for months and months - not even two. I'm not being smug, just reporting that this time round I can tell you that EC isn't 'out there', it just makes physiological sense
