No Spill. No Spout. No worries. The Sassy Cups allow your child to drink anywhere around the rim just like Mommy & Daddy! No hidden areas here, just three simple parts that are all top-rack dishwasher safe. Plus, the insulated design keeps your little ones drinks cooler longer. Transitioning from one drinking method to another can be difficult for baby. Each child is different, so it may take some practice before your child grasps this new concept. Since the drinking action is a little different going from bottle to straw, straw to sippy, sippy to spoutless, and so on, your baby may need a few days to become used to this new method, but be patient, baby will catch on soon!
