it is so hard for people becuase, as I'm sure you have noticed, children in mainstream america, tend to LIVE off of crackers, cereal, cheese , mac and cheese, and the like.
Those turn into a parents crutches in many ways and it is very hard to know what to do for your child that is different then what you do daily.
My neices, for example, refuse to eat anything but mac and cheese, crackers etc. If they had to spend a week with me, they would either starve, or get used to eating a variety of whole foods!
I know it is frustrating, but it is not going to change.
I was thinking about you the other night when I was watching TV and there was a commercial that sent the message the 9 out of 10 peole weren't getting enough healthy whole grains and that they would essentially be working toward heart attack if they didn't eat cereals like honey combs on a daily basis!
It was an appauling commercial, but probably only appauling to you, me, and a handful of other "weirdos" on the non mainstream path.
I know it is hard!
Especially for his type of reactions.
