I've been turning the artificial lights out at sunset lately and using Coleman candle lanterns to light the way for snack, bath and bedtime. It's helped the girls get more calm at night and go to bed quicker.
I wasn't sure how these would work as a candle alternative (you know, like if you're unnerved letting little kids walk around with FIRE or something) but I got them and they're AWESOME!
Just the right size and brightness and the girls love them. They love the candles, too. but these are fun because they're submersible and you can play with them in the bath!
