The sleep of a 2-year-old
At two years sleep looks almost like an adult’s: eighty-minute cycles, one solid night, one nap after lunch.
What changes is what is going on in their head. Imagination develops, and with it the fears: the dark, the noises, what is under the bed. These are not tantrums, and brushing them off with "there is nothing there" never works very well.
The other new thing, for those who have moved to a big bed, is getting out of it. Here too, consistency beats discussion.

The key point at this age
Evening fears are handled during the day
Acknowledging the fear without validating it — "I know you are scared, and I also know nothing can happen to you here" — works better than denying it or going to chase the monster from under the bed, which confirms one could have been there. A warm, dimmed night light helps; blue or bright light delays falling asleep. And the real work happens during the day, talking about the dark when everything is fine, not at 9 p.m. in a dark room.
