Carnival is a good choice because they have some limited hours of group babysitting fo ryour one year old and change diapers -- most other lines don't. I'd avoid the Celebration and Holiday -- they're very old, small ships. The newer ships are Carnival Freedom and Liberty. Carnival has a good youth program so you'll probably enjoy whichever ship you choose.

I'm worried that you will have a hard time finding a cabin that accommodates 5 people? Usually it's just 4?
