Another parent with an ARFID kid here, though it sounds like our case is somewhat different. My kid, almost 16 now, has always had an extremely limited diet repertoire, starting at a failure to switch to non-smooth baby food as a toddler. Early on he exhibited extreme fear reactions to being presented with new foods. Nausea has never really been a huge issue, other than gagging if we tried to force him to try something new.

As he's matured, the reactions are less intense, and with a lot of therapy sessions, most recently with a dietician who also has ARFID, we've made real progress. In our case, that means he's (enthusiastically!) eating cheese pizza, scrambled eggs, and chocolate (but not white) milk, along with the bacon which has been his main protein source since age 3 or so.

Not sure what we'll do when he heads off to college in 2.5 years.

Anyway, if you want to compare notes with another ARFID parent, my email's in my profile.
