Soy Beans

Two days ago he loved them. Ate a whole bowl full. Today it is if I am making him eat gravel. I put one in his mouth and he freaks out. I mean head spinning, screaming his little heart out freak out. I don't understand. I cooked them the exact same way. After pushing them around his tray for a few minutes hoping they would be evaporated into the tray I guess, he finally got bored with that and started to play Indian. Unbeknownst to him he had one stuck on his palm and when he put his hand up to his mouth he put a soybean in. It might as well of been hot lava. He screamed hard and loud and shrekeingly high. He stayed that way until he leaned over to bang his head on his tray and it fell out. Then he was fine. I left him with his tray of 15 soybeans and went to the bathroom. When I came back out, there sat 15 soybeans. What is so different about the soybeans tonight?
