Neurodivergence is a whole different ball game that I'm not clued up on at all, and I'm sure that you are 10000% doing what is best for your daughter! I can only speak of my experience and what I've seen with neurotypical children. George has 4, and I've no doubt that there's some neurodivergence there but the fact that all 4 eat like crap isn't a result of that. When she was weaning Coco she started with fruits and vegetables but very quickly started relying on all the beige stuff and the ready snacks, biscuits etc. Vegans who eat well have a lot of grains, pulses, legumes in their diet and I'd be surprised if any of those 4 have seen a chickpea in their life. At the end of the day, generally speaking, children will eat what they've grown up eating. (again, in neurotypical children, without eating disorders like ARFID etc) A child isn't going to constantly ask for a Linda McCartney sausage roll if they've never had one.
