My mom was reasonably understanding with my food issues. Fortunately I liked raw veggies and such, so she could always give me those. Hotdogs, however, were off limits. I literally could not eat them for how viscerally disgusting they were to me, so she didn't push it.
I mean, what parent wants their kid eating a steady diet of hotdogs anyway?
But I remember being at a friends house when I was very very young, and they tried to make me eat hotdogs. I ended up spewing them out on a napkin, and that was the end of that. No more force-feeding me hotdogs.
