Title: Beware of cracking plastic!
Review: I was happy to find a BPA-free sippy cup with a straw (this was the only I could find) because our speech therapist suggested a straw sippy. They worked great for about a month, but they're not very toddler proof. My son dropped them a couple of times and the ring of plastic around the bottom started to crack. The plastic comes off in sharp small pieces that would NOT be good for him to eat (fortunately he's not sticking everything in his mouth anymore.) It also leaves pretty sharp pieces sticking out. Unfortunately, you can't just pull the plastic piece off because it's glued on.
