You might want to reconsider the 8:00pm seating for dinner. As most dinners last 1 1/2 to 2 hours long your baby would be up till almost 10::00pm. Some people who choose the late seating do so because they want a more adult dinner. You would be unlikely to find many young kids in the dining room for the late seating. In my experience cruising with kids they tend to get pretty worn out by the end of the day. Of course you could always use the babysitting service and enjoy your late night dinner.
