Ravenous

My 5 year old is really driving me crazy these past few days. He has a tendency to talk me into cooking or preparing something for him to eat and then he doesn't want to eat. Or he will ask me for seconds and I will just give him alittle bit and he doesn't eat it. I will even ask him if he is sure he is still hungry before I give it to him. He will pull this a lot at suppertime and then wake up ravenous and demanding breakfast right then and there. Dear son let me wake up first.
