The risk: Several models have been recalled because they pose a potential electrocution and fire hazard, and others have scorched furniture. "There have just been too many fires and reports of problems," says consumer advocate Alan Fields, who advises against these products in his book Baby Bargains. "It's an unnecessary risk for something most kids can do without."
Safe strategy: If you use a warmer, follow the instructions carefully, especially if they recommend adding water. If it's not brand-new, check cpsc.gov to make sure that the model hasn't been recalled. The best solution? Just hold wipes in your hands for a few minutes to warm them up.
