You may want to check and make sure it is alright to take an infant on your cruise as some lines have an age policy (must be 6 mos. for example). We have taken our 7 mos. old on a 15 day Hawaiian cruise on RCL with no problems and you do have to pay a third-person rate for the baby (expensive, since they use no facilties!!). There were at least 20 babies on board with us. You can request a crib for the cabin. There is no care provided for infants, i.e. babysitting. Maybe on the line you cruise you can hire private babysitting - read the small print on the back of a cruise brochure or ask your travel agent. Hope that helps. Congrats on your pregnancy!
