Great ideas on how to clean those things! Even the regular no-spill cups have little crevices in them, like one we hae that has these grooves all the way up the spout... it's way to small to get anything inside! I now use almost exclusively the free-flowing, old-fashioned cup that are just a basic cup and a lid with no frills, which are so much easier to clean, and cost so much less besides. I swear the sippy cup manufacturers are trying to find ways to make the cups get all funky in a couple month sso you have to just throw them out and buy new ones!
