It takes 3 days to die of thirst and if he's nursed at all since birth, and if you were on iv fluids during labour or delivery, he's probably simply not hungry. They don't arrive hungry.
Eat anything you want --yogurt, cereal and graham crackers are not related to milk production, and neither is any other kind of dairy product (what kind of milk do cows make to make milk? grass and water...) or, frankly, any other single, specific food --since there is no food that all humans worldwide or throughout history have eaten, just about everything about eating for milk production is nothing more than regional or cultural wives' tales.
It will help a lot if you keep him on you, preferably on your naked chest. Wrap him on you rather than you wearing something between him and you... and allow him to latch on, explore, taste, smell, bop around and hang out --a 'good' feeding is one that the baby started and ended. No clocks or charts.
