These toilets can smell pretty bad and it's easy to see why some children are afraid of falling in. When you tell your child about camping be sure to include information about the bathrooms. Flush toilets can be loud and are not like the potty at home. If your child will still go on a potty chair you may want to bring one along - just in case. Your young bath roomer may refuse to use this stuff.
Some camps provide little squares of paper.
A parent may be able to use this stuff but a young child might have some problems. Many of the toilet paper dispensers make it quite difficult for you to get the paper off of the roll. This is actually intentional. The idea is that you will use less paper if it is really hard to get it off of the roll. As a former park employee this is the silliest thing I have ever seen.
