For Yellow Nails: 1) scrub your toenails with a nail brush and whitening toothpaste. OR 2) make a paste using 1 tbsp peroxide and 2 1/4 tbsp baking soda. Let this paste sit on your nails for 5 minutes and voila! White nails!
Traveling with young kids made easy: Put an entire outfit (including undies and hair accessories) in a ziploc bag. One bag per day. When you get to the hotel, put the bags in a drawer and they can pick one per day. Huge time saver.
