I'm just as bad with Kaylee's stuff so I'm no help. I would leave little piles on the kitchen counter of the alcohol wipe wrapper, alcohol wipe and last test's test strip. I usually remembered to throw it away when I went to put the needle in the sharps container (we put the cap back on before we put it in the sharps container, so those never turned into trash), but sometimes I would come back an hour later and see my little pile. It's gross and I'm always mad at myself when I see them there.
In the past week when she's been pumping, the trash has decreased considerably since only get a huge amount of trash every three days and that's easy to put in the trash. Just test strips everywhere.
