Dusk-to-Dawn LED Night Lights, 6-Pack
Plug one into every room you stumble through at night and forget about them — a light sensor switches them on at dusk and off at dawn. Six of them cost less than one designer lamp and use about 2 kWh a year.

If you want to fine-tune both sound and light until you find exactly what settles your baby, this one gives you the most combinations to try. With 30 sound options and 12 light colors, you can keep adjusting instead of settling for whatever the machine gives you.
