great eater now picky!

Has anyone else's great eater all the sudden become SUPER picky?? My Sept. 15 little guy had such a good appetite and he would eat anything we gave him. I was so happy. Now all of the sudden he is refusing things he used to love. It's driving me crazy! All I can get him to eat is yogurt, cheese, crackers, and fruit. Anything else I attempt he waves his hands and cries
