Hi. DS has had a gtube for several years. Did you daughter simply have the gtube inserted, or did she have another surgery at the same time? I am assuming that everything is healing really well too
If it was just the gtube, I don't think you are going to have any issues. The only real issue I can think about is if the tube (or button if she has one) comes out. They may not have trained you yet on how to put it back in so you may want to check with the
DCL medical staff that they can reinsert it and get training if you haven't had it yet.
We haven't cruised yet, but I contacted DCL about having an extension cord in case DS is not sleeping near where the few outlets are (for the pump at night.)
I have a travel checklist for our supplies. I have an extra button, extensions, feeding bags, large syringes for feeding without the pump (always a good idea to have a backup to the pump, ours broke the first trip we took with it, thankfully they have fixed that problem now!) the pump power cord, creams, gauze, tape, etc etc etc. The check list is helpful too when you are packing to leave so you don't leave anything in the room.
Good luck and have fun on your trip!
