if you think you can get DS1 to eat anything not on The List, please be my guest. He had several bouts of illness over 4 weeks, and afterwards would only eat white foods; bread, potatoes, bananas, porridge, cheese, pasta
Such a first world problem. How is it that children in Asia manage to eat wholesome meals of rice, veggies, curries, lentils, sushi at an early age?
Also, a more general point, why feed a child fish fingers or nuggets? Why not proper fish and chicken? It is not more expensive. I have seen 6 flash frozen cod at Tesco for a couple of quid. Baked fish, boiled spuds and steamed broccoli is so much better than fish fingers, chips and peas. No difference in price or effort really, but a big difference in the level of processedness of the food.
I read a study once that children who have food like fish fingers and nuggets are not open to trying new flavours. This is because the industry tries to make these processed foods always look and taste the same. But real fish and chicken come in different, shape, texture and taste, and children reared on these are used to different flavours each time, and do not get used to or crave sameness in their meals.
