There really isn't ever a 5 minute window where I know for sure I can be alone in the kitchen. I live with my boyfriend and his mom, uncle, brother and sister in law.
Even if I wait until late at night, my boyfriend's mom will be awake and always comes out into the kitchen to chat when she hears someone. I just don't really want to have to explain it to anyone. If it looks like just the pouch I can make up something other reason for having to boil it.
I plan on using alcohol prep swabs to clean when I need to and just rinse with water during a normal change.
