My little girl is going through this too
maybe/ ask him what he wants for tea??? Take him shopping for food???- get him involved in food prep?? Find they eat more when they ‘help’ cook- my lo not going through this rn - but has gone of his food a few times- I only recently started giving him choice (of a couple of options ) as to what he wants to eat - but think it helps him get more interested in food
Exactly the same right now !!!! She won’t eat dinner Iv tried everything
