*** Helpful Hints
you are out of heat packs, simply use hot water to reheat. It may take
longer but it will still work. Stainless container is also great for
storing & traveling with food with its airtight/leakproof lid. If
you want to use the food warmer as a double boiler, add adequate amount
of water into the stainless container to heat up the water - submerge
baby bottles, baby foods and pouches to warm up and enjoy!
