I've had a hard time getting Jordan to eat for a few days. He wont even eat bananas, raisins, or peanut butter sandwiches, which are his favorites. Why wont he eat, you ask. Well, every time I tell him it's time to eat he says, "cookies, cookies!" That's all he wants. He even woke up a few times last night because he was hungry. I have no idea what to do. Any suggestions?
