There’s a rubber seal inside the lid that stops them leaking. The milk etc can get behind it, where normal washing won’t get. It can get funky if you don’t clean it out.
Parenting mostly isn’t that hard. You just have to keep all the proverbial plates spinning. Unfortunately there are FAR more than you expect, and you never get a break. You will miss some, then beat yourself up for missing something so simple.
As a childless person… I don’t get it.
Is it like a rubber seal that keeps they lid on like in some other things meant to hold liquid or is it some other sippy cup related contraption

I see, thanks for the clarification!
Have you ever used a water bottle? They have a rubber seal in the lid that needs to be removed for cleaning. Same concept with sippy cups.
