Here are some miscellenaeous bedwetting products that are also really helpful.

 
Dr. Smith's Diaper Ointment, 3-Ounce Tubes (Pack of 2)
My review: This stuff is really good because it doesn't have steroids or antibiotics - just non-greasy, unscented relief.

My Review: OK - these are great for lining a sleeping bag, or for tucking into the trunk of your car... just in case. They're cheap, so you can chuck them after using them - or hose them off. 

Soaker Mattress Pad

My Review: These are great because mattresses aren't cheap! One good soaking and you'll never get the odor and stain out. If you protect your mattress with a good quality mattress cover, it'll save you money and peace of mind. When there's an accident, just be sure to shoot the cover with some enzyme-based cleaner.
