My ds5 has started to get really fussy with food. On the waiting list for Ados and expecting asd diagnosis. He's always been a bit picky but will usually have a good appetite if it's something he likes. Lately he's been refusing to eat meals he's liked in the past, but his language is limited to just declaring something's disgusting or yuck, not able to articulate why he doesn't like it. If I serve the same thing a week later he might eat it without any complaint. He will sometimes say yes to a meal, then when I make it refuses. When I try and encourage him to eat something he gets really anxious.
I don't want to get into the habit of making dish after dish for it to be refused, but also worry about getting hardly any food into him. Yesterday he would only eat a bite of toast for breakfast, thankfully ate all his mac and cheese at lunch, but barely even nibbled the edges of a wrap from a chicken fajita for dinner (previously would happily eat all).
What can I do? Every meal feels like a battle. I try and gently encourage, give lots of praise for when he does eat, but don't want to stress him out and worsen the situation.
