Hi,
so glad surgery is over and went well.....I completely agree with Pooka that they are feeding him WAY too soon! That is why he is nauseated. Give him a few days of either nothing by mouth or just a few sips here and there, to give his gut a chance to wake up. Right now he needs good pain control.
I am a nurse who has had 3 major back surgeries, one complicated by a very painful paralytic ileus. I am incredibly familiar with post-op nausea and it is absolutely miserable. Early food makes it much worse. Please give your son's belly a chance to wake up, then think about restarting solids. Sometimes nurses will try to push food during these early post-op days with extreme nausea, and it is a huge mistake. Your son will be fine for a few days without eating much.
