I completely understand. My daughter had to be sedated for a CAT scan on her head. The only advice I can give you is the medicine that they gave my daughter to sedate her made her very gassy afterwards so keep that in mind and ask the doc if this happens. Try to feed him as close to the cut off time as possible. They should also have him scheduled first thing in the morning because it is harder for babies to go without the food. If they don't call and request that he is first thing if at all possible. Also try to take someone with you to help take care of him. You will be stressed out and if you have someone with you they would be good moral support. Good luck.
