Hi S.,
Here's my advice...
Start with one meal let's say breakfast. You can give him pancakes with butter (you can even get frozen veggies and blend up and put in them and then cook them), toast, french tost sticks, biscuit with butter. When you off these to him keep giving it to him for a week and eliminate something that would normally be "baby food type", you can also try regular oatmeal in different flavors. Try scrambled eggs, sausage links, sausage patties, taster strudles are good also, along with waffles. Load it with butter and let it melt, once you get him going back off a little on how much butter you put on it. You have to make the food more appleaing to him and tast better than baby food. And remember thjat we don't need all the fat content in our food but he does, so he needs the fat in butter and things like this.
For lunch make him a grilled cheese (make sure you let it cool real good), mac and cheese, quesadillas, chicken nuggets, hot dogs (cut them in 1/4ths), fish sticks. Don't forget pizza.
Start small and work up but remember take a way something of baby food. Also you can buy the individual fruti cups and applesauces. And you can buy the smaller cans of vegetables, another option is frozen vegetables. My daycare kids like the canned veggies better than frozen.
And by the way I wouldn't eat those baby meats either, yuck. He may not be eating because of what you are feeding him. Find something he can eat and then go with it. Start adding in other things.
FYI, my 4th dhild wasd on table food by the time she was 7 months, she wanted noth9ing to do with baby food anymore. She also didn't have any teeth. But they don't need teeth to chew their food, their gums are very powerful.
For snacks my daycare kids love yogurt burst cheerios, any kind of crackers. Oh and they have these new mini muffin tops out now (eggo makes them, they love those. we had those for snack). I have plenty more but I will leave you with that much, W.
