We use the VTech night light, which plays different white noise sounds, stories or lullabies and shows the temperature of the room xx
I have the jolywell egg night light & I honestly love it, it’s cute and the lights are adjustable
I have a humidifier that has a very soft glow to it that we use, and honestly I've moved past white noise, she sleeps through the TV and noises during the day and I throw on some disney instrumental music for at night
