After I posted my suggestion about the same idea, I thought about what happens when child wakes up in the dark and needs to get out of bed and over to the switch to turn it back on.

Sensor, he could just wave his hand

Put a ceiling one in.

Then you can turn it off when not needed via the light switch.

Another option is to use a pir bedside lamp, they probably do mains ones as well.

Or put a Philips Hue (white!) bulb in the ceiling fitting, which can be remotely controlled using the Philips app. on a phone (Bluetooth) theoretically from anywhere within 10 meters.
If the wall switch is subsequently operated off-on, the light would come back on, so you still have 'normal' functionality from the light switch, but the added ability to turn the bulb off remotely when it's on (which you can also automate if you wish )
No wiring changes needed!
