OP, I'm a nanny and I have been a preschool teacher for eight years. The key with children is not to allow them control of their diet yet at the same time do. Offer him a variety of food items, and let him eat what he wants from the plate of food. If he doesn't want to eat anything you've given him, then let him down and don't sweat it. Children will not starve themselves I promise! Be consistent with offering him foods, offer him food at ever eating time his schedule is on. Teeth are a huge issue with babies ad toddlers, as well as food textures. If your baby is teething, chances are something cool with sooth his gums and make him less grouchy/against eating. They make pouches you can shove frozen fruits or anything cold or frozen in. The child can hold them, and eat them at his leisure. I'm not sure what they are called, but it looks like a net on a ring. Now, textures are a different issue. As children grow, their soft pallet and taste buds change as well. If you notice your baby isn't into a certain food, asses the texture of it. Is it too hard, soft, mushy,etc. Then, try something with an opposite texture. Good luck, children can stress you out without even trying I know!

Then make the food on the floor
