I just used a lamp initially in our room, but you get so adept at getting up at night now I don't turn anything on.

In Darcy's room someone gave us a cool nightlight. It's Winnie the Pooh and is battery powered and it turns off after 10 minutes. Good enough to check on bub/find the dummy etc. And it gives her something to look at as she drifts off. It's tied onto the side of the cot out of her reach.
