Turn off lights
Flicking the lamp off isn't a small move, it's the day's full stop. Many children aren't protesting sleep, they're protesting the switch from light to dark itself. When turning off shows up as an upcoming step, it stops being a surprise. The pictures below show the way there.

About this visual support
Darkness never arrives on command. The second the lamp goes off, the whole room shifts: familiar shapes turn into grey outlines, sounds carry further, the body senses there is nothing left to look at. For a tired child still holding on to the day, the click can be the drop that tips protest over.
When turning off is built in as a visible step in the evening routine, it stops being a sudden ending. Pictures can show the ceiling light on, the light dimmed, a small night light, the main light off. Then the child sees the transition is planned and has a halfway stop, not one single leap from bright to black.
One practical tip: tie the actual switch-off to a tiny act the child gets to do themselves. Pressing the button, pulling the cord, blowing toward the lamp. That way the control stays on the child's side at the very moment the room changes. If you'd like the whole evening routine as a string of pictures on a phone, Routined is free to try for fourteen days.
