Yes....this is not good but this works!!! For those who have had this problem, this is the best solution I have found.
You can eliminate bed-wetting stains or pet urine stains on a mattress using baking soda. If the urine has soaked into the mattress quite a bit, baking soda can remedy the situation. Simply sprinkle a good amount of baking soda onto the affected area. It will actually lift the stain and smell out of the mattress. After it dries, brush off or vacuum up the baking soda residue. You may have to repeat this process several times for optimal results.
If your kids are dying to have a "sleep over" but are too young, try having a pretend one. Invite the friend over and leave the kids with a baby sitter while you and the parents go out for dinner. Let the kids have their sleeping bags and PJ's and go to sleep. When they wake up in the morning asking where their friend is, say they just left!
