my 19 yo toddler rejects home food at home (he would rather starve) and also when we bring homecooked food out. It seems like he likes salty food. is it better to feed him salty food so that he will eat? sigh .

It depends how you want to think. Is t really too bland? For me, i am open to them eating outside food. just that i make them drink lots of water after that. food too bland, they won't eat too. maybe find other ways to spice up your home cook food to make him accept it at home first?
