After having a baby you can have sutures that are inflamed. Soaking in soda water is necessary. To make it easy to slide around a clean large garbage bag over the toilet seat. Then press the middle part and in some there is a bowl. You fill it with some soda and warm water. Now you sit on it for weeks. When you're done you prick a hole in the middle and the dirty soda water immediately drains into the toilet. Then remove the garbage bag from the toilet seat and throw it away. Convenient to do and very hygienic.
