Especially in this weather??? Only just started weaning ds and haven't really got a clue, so say I defrost a couple of cubes of sweet potato and put 'em in a sealed tupperware, can I chuck it in my bag at 10am, go out and feed it to him at say 12.30pm? Not usually got access to a fridge cos might take him to an activity or mother baby gp and then go to cafe/pub garden for lunch.
