I nightweaned my DD at about 18 months. It took 2 nights, was incredibly easy, and so I knew she could handle it. If she had resisted, I would have waited another month or two and tried again.
I mainly waited until her molars and incisors came in all the way--they were so incredibly painful for her that I didn't think it was fair to try to nightwean her while they were coming in. At 18 months, she was also able to understand pretty well that mama just needed some more sleep at night. She was starting to develop some empathy by that age and could begin to understand why I felt I needed to nightwean her (something I don't think she could have done at a younger age).

- stepping down.

she still gets a little nursy in the morning when we are both awake, though.
