I think all the professional advice we got for our son's eating disorder early on prevented it actually being diagnosed. SLP said "he swallows just fine" and OT was all about "just take a bite." In fact, the ARFID therapy we were referred to is all about "become familiar with the new food" in a way that makes the aversion worse. At this point we don't give a shit about new foods, we just want him to not starve!
no to OT and SLP
