Is the tube of Vaseline a good substitute for butt cream while out and about? Going to the zoo and my kids never have issues while out, but didn’t wanna be SOL with something like this. I figured it would have to be a good “bandaid” until we get home. At the very least, in case one of my kids end up a little raw. I’m mostly concerned about my 4 year old since she’s still potty training and will be walking around.
