I don't recall having food issues until I started school.
Starting school for me was, for several reasons, hard, but the overriding memories of it are focused on food, and even drink (school milk, even though I don't dislike milk in itself).
My parents were not lax, but I don't ever remember being smacked until I started school - after a few days of school, I was hysterically crying one evening, saying that I didn't want to go to school again. One of my parents eventually lost control and smacked me, though was instantly horrified and apologetic as red marks appeared on my leg.
I spent the whole of my school years avoiding school dinners.
Anyway, looking back, it is the smell of the food and drink that sticks in my mind. Even thinking about it brings back memories of how those smells made me feel!
In fact, whenever we (occasionally) pass the building that used to house that infant school, I can still be overwhelmed by memories of the smells and emotions that food evoked in that stage of my life.
Food issues are not always about the taste of the food itself. It can be so much more complex than that.
With hindsight, I have realised that I only had/ have food issues when I am out of my depth. They are not voluntary, and I don't think that there is anything my parents could have done that would have made any difference.
