What are the recommended boiler or cooker which I can use to cook porridge at work and bring home in time to feed baby? TIA

None of my friends cooked at their workplace. Instead, they use a slow cooker when they want to prepare meals in advance. A few of them would cook porridge overnight and put it into a thermos to bring along to the childcare centre. I'm thinking you could consider doing the same but cooking in the morning so that you can serve it for dinner after you are back from work. Just a suggestion. :)
