Worried about my son

Hey 65Vart, sorry to hear this, unfortunately cant offer much advice here, but me being a "big" kid, could you make a game out of eating?? Let Aiden pick something?? Kind of like the "shell" game where you uncover something and he can have that to eat? The idea of something aromatic is a good one too as if it pleases his sense of smell he may take more of a liking to it. Good luck and our thoughts are with you and Aiden and your wife
