Getting Baby to Eat

My darling child will not eat new foods. He will eat all the veggie and fruit purees that he tries, he will eat Puffs, Crunchies, and Arrowroot cookies. He will not touch nearly every table food we have attempted. It is starting to stress me out because there is no way he is getting the calories he needs as he has slowed down on nursing, too. I have tried chicken, beef, scrambled eggs, black beans, peas, pasta, cheese, buttered toast, pancake, biscuit, and more. How can I get some calories in this kid??? Any advice?
