I know a lot of people here swear by the ZoLi. I need a new straw sippy cup for Liv. We were using Tommee Tippee ones, but they require a TON of work, even for me, to get the liquid out. She can drink out of a normal straw, so I dont think that much work should be necessary. Is the ZoLi straw the type they have to bite on? and is it difficult to get the drink out?
