I know I'm bu but I'm posting here for traffic
My grandson is 18 and lives with us. Ever since he was young he's been a fussy eater and when he was at secondary school he never ate breakfast (he'd occasionally have toast) and he wouldn't eat any lunch but he would always eat anything I cooked for dinner. And he'd always eat a Sunday roast without any problems. Lockdown last year he didn't eat much in a day but he would always eat dinner. He went back to college and he was the same as before. Recently he's wanted McDonald's everyday for dinner and he says he 'doesn't like' what I cook even though he previously ate it. Today he said he doesn't want a Sunday roast for dinner and he wants McDonald's. I've said no (he said he doesn't have any money so I'd be paying for it) and he said he won't eat then. I obviously want him to eat and he is underweight but I don't want him to only eat McDonald's! When I asked what he does like he says he doesn't know
I'm at my wits end!
