Picky Eater!!

Leon has decided lately that he doesn't like vegetables! I dont' know how to get him to eat them. Does anyone have any suggestions on how to get him to eat them? The main ones I have problems with are green beans and carrots. He'll eat corn and peas...but he won't eat the other two. Daycare says he eats "great" there so I'm going to check with them and see what exactly great is to them...does he eat EVERYTHING and that's great..is he actually eating his vegetables there? If he is then I won't be as pushy at home...but he has GOT to eat them. Skip and I don't like broccoli but if I can get Leon to eat it...I'll buy it for him! I just don't know what else to try. He likes potatoes but the normal stuff he won't touch. He actually went down for his nap today without lunch because he wouldn't eat...green beans..he wouldn't even touch them. So, I don't know if he's just so tired he wants to sleep and he'll eat when he gets up or what. I'll try again when he gets up...hopefully it works. Does anyone have any tips on how to get him to eat his vegetables? I'm at a loss!
