Hi sarah
your daughter has already had her IVIg by now - sorry that I did not read this sooner.
Hopefully everything will be okay. My daughter did not have any problems with the IVIg. She did start to react to it after several months, so they just switched the brand. I would give her Tylenol in the morning before we would leave as she did develope headaches, and they would give her Benadryl when we got there. The Benadryl is good because it does cause drowsiness, which could be a benefit for your little one.
It can be awfully scary - especially with a three year old - they are not always the easiest to deal with.
I hope everything goes (went) well.
Good luck.
