When you have allergies or food intolerances, it is very common, in my experience, for people, large or small not to feel particularly excited about food in general. Maybe the taste buds are affected, the fear of what happens when you may eat the wrong thing or just that you feel better when you keep to a restricted diet, avoiding the variety.
As a parent this can be frustrating as we are worried that a child is not getting all the vitamins and minerals they need as they are not eating the wide variety of foods from all the food groups that we are taught they should eat. I remember by fussy eater as a toddler declaring to me 'Mum don't you know I only eat chips and coke." As a school boy he declared to a friend's mother on a play date that he was allergic to all the foods presented and that he could only eat a vegemite sandwich.
In my opinion, you need to work with what you have been given. That being said here a few tips, I found helpful with my fussy eater.
Get Cooking-Once the child is old enough, keep then involved in the food preparation process. They are far more likely to eat what they have helped make.
Healthy Choices Only -Keep food choices in the house to just fresh, healthy choices. If you are going to have some prepackaged snacks, choose only those that have high nutritional value. By limiting choice, believe me, you limit the arguments.
Variety-Give them the same food from morning until night each day if they wish, maybe just put one 'different" item on the plate or in the lunch box. (Best to try at home as it most likely will end up in the bin at school)
Don't stress- Their taste buds are changing all the time so expect that the foods you confidently packed in one week, won't be eaten the next. Go back and discuss with them the options and what they want now.
Don't be afraid-They will not starve to death, be rest assured. Give them a good-quality supplement in a liquid form, crushed; however, you can get it into them. I have resorted to bribery on many occasions.
Good luck, mine has mostly grown out of it at the age of 12. I still limit the choices in the house and generally pack the same thing every other day. This boy is a creature of habit and doesn't respond well to surprises.
