Why yes he is. You see Friday night, our son said, "I see your tickets, but I'm going to raise you puking." We had explained to him the new ticket system, being that he gets two tickets each night and each time we have to come back to his room, he loses a ticket. Once he's out of tickets, we don't go back into his room. He went to bed with no problems and was sleeping soundly until midnight when we went to bed. At that point he began puking in steady succession. By 4:00 am, he had thrown up 6 times, and we were completely out of his sheets and blankets, so he spent the rest of the night using a beach towel.
When he woke up on Saturday, he seemed to feel better, but he had very little appetite all day. We had friends over for dinner, and right in the middle of having a great time with their kids, he thew up all over the table. He puked two more times before we got him upstairs. We gave him a bath, flooded him with Pedialyte, and put him to bed. He got a slow start this morning, but so far, no puking incidents and he appears back to normal!
