Question about 1 yr old feedings?

my son just turned one... and im worried that since he's weaned off his formula he's not getting what he needs.. he doesn't like eating alot of meats, although occasionally a little boiled chicken he'll eat... he ususally eats cereal in the morning, and throughout the day id say about 5 servings of fruit and 5 of vegetables... he doesn't drink alot of anything, but he'll have about 16 oz of milk a day, and maybe 6 of juice or water.... i tried buying gerber puffs or something he would enjoy eating but i dont want him relying on those kinds of foods for much. his stools are usually a little harder then they used to be, and are somewhat less frequent. his urine output is good, i have a wet diaper every 3 or 4 hours... should i be worried? does this sound healthy ?
