Toss a light in the bathtub. Waterproof Tub Lights are a fun way to make bathtime a little more peaceful. Friends of ours installed a dimmer switch for their overhead bathroom lights, and now when they toss the kids in the tub, they toss a few of these in as well. Ditching the institutional overhead lighting can sometimes turn a recalcitrant bather into an eager one. Or so we are told. Frankly, we think these might be equally as good for parents once the kids are asleep - a hot bath, a glass of wine, and Waterproof Tub Lights instead of candles. You know...for all that me time parents have. $14.95. Good Posts: • Gelli Baff. • Metalarte's Waterproof Lamps. • Survey: Music in the Shower.
