Title: Don't buy if your child has any teeth!
Review: This sippy cup, in theory, is good. However, if your child has any teeth - even one - they will quickly pierce the softy part that they suck on, releasing a flow of whatever liquid contents were contained down their shirt. At that point, the cup is garbage bound because there is no possible way to fix it. Dr. Browns does a good job with bottles, but hasn't figured out the next step quite yet.
