C.,
We just got back from a 7 night cruise on Costa Med, we sailed with both our girls, 3 1/2 yrs and 11 months.
Here are some of the things that worked well for us.
- if Colton will be sleeping in a crib/pak-n-play take your own if you have a small travel size one. We used one Costa provided (I am not sure which line you're sailing on, so this may not apply) and it was very nice, but very large and took up a lot of room, our travel size one would have worked much better
- take an over the door hanging shoe holder (I got one cheap at Walmart) hang this on the inside of your closet door and use it to keep clutter off what little surface space you have. I used every opening, you'll be amazed at how this helps.
- snacks helped a great deal, I brought raisins and cherrios for our little one.
- don't forget the sippy cups, I only brought one and then also packed a few ounces of liquid dish soap and a handi-wipe rag and washed it and the bottles nightly.
- we brought and used occasionally our portable highchair (it's a chicco like this one.. http://www.highchairs.com/assets/product_images/200/10183...) when the ones on the ship were all being used.
- umbrella stroller was a life saver (our little one was very content just to sit back and relax in this most of the time)
- we let our little one have some floor time in the empty lounges during the day, she liked crawling and cruising the furniture and it also gave her a chance to burn off some energy.
- we brought and used the Munchkin inflatable duck tub (sold at Target) as a bath tub in the shower. It worked out great, I also have heard people used this as a pool up on deck since most cruise lines don't have a swim area for diapered children.
- we didn't bring many toys for her, a few board books and some blocks, she only played with them in the room. Colton might prefer more.
- hats!!! Our little one has NO hair so a hat was very important for us, but I tried to keep us in the shade as much as possible up on deck.
- I brought a washable bib with us, saved me having to worry about a dirty cloth bib, since I could use a wipe to clean it off and saved a lot of clothes from getting stained from all that wonderful food that she enjoyed so much!
- ask and you shall receive! if you don't find something you need for Colton ask a staff member, we found that they were more than willing to help and they especially LOVED our little one and the other babies on board.
- diapers!!! I thought I was over doing it, but found I actually planned it just right, we brought a sleeve of diapers with us...I think it was maybe 50 and actually only had a handful left over....wipes I didn't get so right, I only packed one tub-full and one refill and ended up buying more at one of our stops. A full tub and two refills would have worked out fine.
- I also brought with us zip-lock baggies, I already use these in my diaper bag (backpack) to keep things organized but the extras helped with odds and ends.
- I brought infant Tylenol and Motrin as a 'just in case' we never had to use it but she did end up cutting a tooth while we were on our trip.
OK, so maybe that's more than you needed, I hope it helps, please ask if you are wondering about something in particular.
I didn't bring any 'baby food' as our little one is eating all table food so she just ate what they had. She is still getting formula in her bottles, 2 bottles a day 4oz formula/4oz milk each. I brought a small can of formula with us and had some left over (not sure if you are FF or BF).
Have a great time!
