I actually have no idea if my kids would sleep without a night light or not. We put them in their rooms when they moved to big beds so that if they got out of their bed in the MOTN at least they wouldn't run into anything or trip. I'm thinking if we took them out now they would notice and want them back. LO1's light is pretty dim but we got LO2 a little fish tank looking one (it's so cool!) but it's pretty bright.
Does your LO need a nightlight to sleep?
