Portable Potty Seat and Regular Plastic Bags

Sorry for the late response, but I wanted to share with you what we use. I have the Potette Plus portable potty as well, and have found that the 4 gallon wastebasket size trash bags work perfectly in it. Much cheaper than the refill bags. I like the Giant brand ones, just because they seem to be strong and inexpensive. When I'm running low on them I have to admit I have also let my girls just sit on it and pee in the grass though. I also keep a package of wipes and hand sanitizer in a drawstring backpack with the potty seat and bags. This thing is probably the single best baby/kid product I've ever had!

I've never used a portable seat for my guy, though we took his regular potty in the car a couple of times when he first trained, and he just used it once.

My worry with regular grocery store plastic bags is that they usually have little holes where there are gaps in the seams and they could leak :-/ I would spend the $15 for the refill bags, it's really only 50 cents a bag, and you won't have to waste them if she doesn't go. You can always finish using them after your trip or with the twins when they need them.

I have used regular plastic bags in ours before, but I THINK they were from my box of new bags from Sams. If you use bags from the store, you could check them for holes beforehand (maybe even run water in them & see if it leaks? then let them dry of course). Maybe even put a bag inside a bag. You will also want to take a roll of paper towels so that you can put some in the bag to soak up the....liquid :)

My cousin who has 4 children under 11 and routinely travels back and forth to the US from England does this.

She uses heavy duty Kotex in the potty for training. Kotex soaks up the liquid. She practices this in flight with her children as to not drag all 4 to the bathroom routinely.

As crazy as I I think she is to keep having babies, she had some brilliant ideas at times!!
Just a thought.

I have a Potette Plus potty which is similar to what you've described with disposable bags that can be used with it. I have used grocery bags with success though sometimes I double bag them. Most frequently though, I've just let my daughter sit on it with no bag inside and pee right on the grass or street. Sorry if that disgusts other people but it makes it much simpler and I figure if everyone else's dog can do it, my daughter can :) I keep a box of tissues or roll of toilet paper in the car as well to use for wiping as well as a little container of disinfecting wipes. Good luck on your trip!

I used Walmart bags. I did make sure that they didn't have holes in the bottom. I put the contents in the bottom of the bag, twisted it very low then turned the bag inside outside of itself. Then tied the handles together. I know, that sounds complicated.

They work just fine, if you are in doubt then dump the contents in the first Walmart bag, tie it shut, drop it in another one and tie it shut.

Be sure to load up several empty gallon jugs with tap water. You can use the water to rinse the potty container out after use. That way the car won't smell.

With kids that small you might be able to get a great deal of travel done when they are sleeping but your 3 year old, if awake, is going to need a break every couple of hours at least. We always stopped every 2 hours so that we could let them run and play. We would stop at places that had playgrounds, like parks if we had snacks with us, places like McDonalds or Burger King if we needed to buy snacks. It sure broke up the trip.

If you can start late in the day after dinner, just do dinner then load up immed. You should get to your destination by midnight with no stops.

I don't know about this situation directly, but maybe you could also use gallon Ziplock/Hefty baggies inside the WalMart bag and seal it before throwing away.

I misread your question. Disregard my previous answer.
