I know this is a ridiculous question, but I just booked a reservation for August 2018 for my wife, older daughter (3) and daughter-on-the-way (due November 2017). How should I go about linking (or not linking) the reservation in My Disney Experience? Should I make a "controlled by" guest profile for my second daughter with a made up birthday and change the birthday to her real one once she's born? Or not add her name to the reservation at all yet? Or add it but not try to create a profile for her until she's born? I'm trying to accomplish this without needing to dial tech support ten times down the line to get it all sorted out.
