Hi E.!
I have done it with a 6 month old and a 5 yr old (for my sister's wedding). It is not easy, but it's "do-able".
I packed with the attitude that I was on a desert Island, and there was nothing for my baby. Then, I organized myself with a back pack that I carried for the trip through the airport, etc....I had another carry-on that was backup for myself and baby, if our luggage was lost, I had 2 full days worth. I'm glad that I packed with this attitude, I had everything I needed, and never had to try to purchase anything. As a mom, it's a secure feeling that your baby has everything from diapers to mylanta!
The first thing you need to know is that if you have a nice big "cadillac" stroller........it won't work for this trip. You need a simple foldup one that can hide in a corner. I bought one with a "canopy" and a basket underneath to hold things. Then I added a mesh basket on the handles of the stroller. I found one cheap at Burlington Coat Factory. Anyway, this stroller "fits" wherever you will need to go, the other strollers will not.
I packed one (hard) suitcase with all the 60 jars of baby food, spoons, Formula, etc... I packed enough for 2 days to travel with me in case of luggage being lost.
I packed One soft suitcase with 80 diapers, which I could fold away and put in the other one for the trip home.
I also had a "packback". I used Ziploc baggies to hold everything like my meds, baby meds, smaller baggies, diaper changing stuff (desitin), a formula bag. Which brings up a good point. I switch to Playtex bottles for this trip. They have the disposable liners, so I didn't have to clean only the nipples. Also, I used the "singles" of Formula. You need to investigate traveling with any liquid at all even for babies. So much has changed since 911. I think you will need to purchase any water on the plane. So, travel with cash.
I did bring a monitor, but I didn't use it.
They have highchairs, just bring wipee's :o) The charis are always in "high-demand".........
They didn't have any baby food, diapers, or anything to buy for emergencies......that may have changed, but I'd be prepared.
There were no changing station in the bathrooms, so everything was done in front of all the passengers :o) I got over it by the end of the first day. I just made sure to WIPE the vinyl couch I used so if anyone was watching, they know that I cared :O)
I used the ship's water for everything, even the bottles he drank. My son is still here so I guess it's ok :o) I asked the Steward (who took care of our room) to please bring me a small container of dish soap, and a couple of extra hand towels, and he did.
The pool kept my son clean.........it was too difficult to do bath's. Or, you could always try to hold him while you shower, there just isn't enough room.
The rooms are pretty small, and they do have port-a-cribs, but they take up the whole area. You should request one, then give it back if it doesn't work for you. I don't know which type of room you have.
Yes, there is a laundry service available. I cannot remember if they do it for you, or if you can do it for yourself.
E., only the first couple of days are the hardest until you've established a new routine. I have other suggestions, but don't want to over-load you if you don't need/want the info. The main thing was the stroller, though, having that simple stroller was the best thing I ever took. It saved my back!
Anyway, I hope that some of this info helps you to pack. Yes, 10 days is a long trip in a suitcase, especially with a baby........and believe me I know!
Good Luck, E.! Have a nice trip, and let me know if i can give you anymore info :o)
