Because I am currently pregnant, I will need to change the date of our 4 night Dream cruise booked on board last May. Work schedules allow us to move the date to either Dec. 2018 or May 2019 (when itineraries are announced). Dec. would mean we would be traveling with a 9 month old and May would mean a 14 month old. (We also have a 4 year old.) Does anyone have any experience traveling/cruising with either/both of these ages?
