E.N.
When he is really hungry he will eat. Just don't let him eat junk. Make him a meal and when he's it's lunch time set him down to eat. If he doesn't eat it, keep it in the fridge. When he wants something to eat, heat that up and don't let him eat anything else until he eats that. I know that's hard to do because you want him to eat anything, but as long as he is drinking, advice the doctor gave us, he will be fine.
