Baby has to be over 6 months otherwise not allowed. No baby food so take your own, not allowed in pools because still in daipers, baby pays the full 3/4th passenger price, no babysitting facilities as not a year old, 45min mother and baby bonding session once a day......to be honest I think cruising with a baby falls into the 'too hard' category, why not leave it a few years and then go (or why not leave it at home with granny and go yourselves) (bet I'll get flamed for that one!!!!).
There are usually minmum ages for infants, usually around six months. On P&O, there are many cruises where kids go free outside of school holidays. They also have excellent well supervised child activities split into four age groups. There is also a night nursery.
You need to state the age of the infant. For instance infants under 12 months are no longer allowed & clubs & activities are variable relating to age. Regards Wilba.
Addendum: Age 12 months relates to Transatlantic. 6 months or Europe.
We were on Independence last month with our nearly 3 year old who loved it. Independence has a great water area for younsters, the H20 zone, but children have to be potty trained to use it. Although there is a small area for toddlers/babies in nappies. There are four hour long sessions per day put on for the under threes (which you have to attend with them) split into 6 - 18 months and 18 - 36 months. We attended a couple but our son was just as happy walking around the ship, playing mini golf and watching people on the flowrider. We went on the Navigator last year (when he was 22 months) and he was no trouble at all, so dont leave him/her at home, take them with you and have a great time.
