I don’t know if this will ring bells for anyone, it does for me – thought I’d post it just in case anyone has any thoughts. I found this in an article about research on restoring normal growth in infantile feeding disorders:
“Infantile anorexia, unlike so-called “picky eating,” is a subtype of infantile feeding disorder, and is characterized by failure to gain weight or weight loss over at least 1 month, rare interest in food or expression of hunger, an age of onset before the child is 3 years old, and the exclusion of trauma to the oropharyngeal area or other medical conditions.”
Honestly, the waters are so muddy. That definition fits me perfectly, and it contrasts “infantile anorexia” with “picky eating”, which would imply that they have got a definition of picky eating, which is more than we have managed to find… That’s another one for me to chase up, I guess.
