I'm the family cruise editor here and we took our son on two cruises last year when he was 7 and 9 months old. Be prepared to bring a lot of baby "stuff" with you! You should read the article I wrote on the family section of this site called "Bringing the Baby." It gives you lots of practical tips. Feel free to ask any additional questions after reading it.

Re: Re: 12mth old on NCL Sky -any advice or comments
NCL has absolutely no babysitting for this age group. Be prepared to have your baby with you the whole time. Unless you are bringing someone to help you. If not try to stick to your baby's schedule for feeding, and sleeping. Good Luck and have a great trip.
