2 year old won't eat solids

He'll eat crackers, PBJ. But for entrees, he'll only eat yogurt, oatmeal, food pouches. Doctor said to only give him water for breakfast, until 12, and have some solids out for him to get when he's ready. I have cut-up hotdogs and blueberries out. 2 days, and he couldn't care less about skipping breakfast. I had to give him a food pouch for dinner lastnight. I'm skipping snacks. I try to eat his hotdog and blueberries in front of him. Nothing works. He had a sandwich for lunch all day. They say kids will eat when they're hungry. Well apparently he can go without eating.

ANYONE ELSE HAVE A SUPER STUBBORN TODDLER WHO ONLY WANTS BABY FOOD?!?!?!?
