Self Heat/Heat Sensitive Baby Bottles  have a system inbuilt in the bottle that heats the milk without using batteries or a power cable. Right now there are two products that fits this category… the Yoomi and Iiamo.  I wouldn’t say this was the ideal way to heat bottles for twins and triplets on a regular basis but having used car charged baby bottle warmers for my triplets when we have been travelling, they are not great, so perhaps these self heating bottles are ideal for travelling.
