Request for suggestions on modifying a sippy cup lid
Hello, I have a bunch of sippy cups, and there are some I'd actually like to use. The rate of flow on any sippy cup is designed for a child (Even the ones from A little luv co, the ones I want to use) how, specifically should one go about modifying the spout to obtain a faster flow? Not too fast, mind you, I like cups with lids for reasons other than just, well, the reason I'm asking here.
