I think this is one thing that intimidated me the most when I first started cloth diapering. We were facing a 4+ hour family trip with all 3 kids in my Toyota Camry. Normally it’s quite a roomy vehicle, but once you cram two car seats in the back, and a 10 y.o. between them, it can feel VERY small. We had two full-size suitcases in the trunk, and packed all the diapers into a smaller suitcase. It did feel a bit ridiculous, I mean, really? A suitcase of diapers? It was sooooo worth it, though!
We made the first two hours of the trip with no problem, stopped for lunch, to stretch, and for our first diaper change. I had brought along two wetbags for the diaper bag, and my large pail liner for using in the hotel room. I wound up putting the dirty diaper in the pail liner and tossing it in the trunk before getting on our way. The next two days were filled with lots of amusement park fun, and cloth-diapering while out and about on vacation didn’t feel any different than cloth-diapering while being at home. I DID make sure to book a hotel room with laundry facilities, because I did not have enough diapers to last me the week without washing (and that would probably have gotten rather stinky!). The biggest drawback was feeling anxiety around leaving the laundry room while washing the diapers… I was so paranoid someone would steal them! I have no clue why, as I never even saw another person in there, but I was SURE some other horrible cloth diaper addict was going to come in, see my pretty diapers tumbling around, and take off with them. So I took a book, and spent a few hours reading while my diapers washed. The last wash day before heading home I finally felt comfortable enough to leave them unattended, and felt ridiculous for not doing it sooner!
Another trip we actually used flats and handwashing like the challenge we did last year. This time we were spending 3 days camping with the kids. This time I kept it MUCH simpler, as 24 flats, and a few covers don’t require NEARLY as much space as a suitcase of pockets and fitteds. I also made a camp-style washer (video tut here). As the diapers got dirty, I’d rinse, then soak them in the washer bucket. I washed them once a day, usually during the baby’s naptime, and then line-dried them. I did choose to fold and snappi the flats on, instead of pad-folding them, to avoid getting the covers dirty. It worked marvelously! I’m still very impressed at how easy flats handwash, and at how fast they dry. There’s definitely something to be said about keeping it simple!
After those two trips, nothing really scared me about cloth-diapering while on vacation. I think the hardest part is figuring out a plan that’ll work well, and then finding space to pack the pocket diapers if you aren’t using flats/covers. We have never flown with cloth diapers, and I imagine having a suitcase just for diapers would be rather frustrating with the extra baggage fees, especially if your baby is young enough to fly in your lap and not need their own ticket!
