Ah, the Sippy Cups of Doom! I don't know why this little trick hasn't been discovered sooner, but apparently kids have been known to chew through the plastic spout of these Playskool No Spill Toddler Sippy Cups, creating a choking hazard. 36 reports of chewed-through spouts have been reported, with likely hundreds if not thousands more unreported. I say this because my older son used to take his cups apart and chew on the squishy drip-prevention insert thing, and I can easily see how these things get chewed through. Hey, some kids are oral, you know?
About 84,000 of these cups were sold at CVS pharmacies across the US from September 2006 through April 2007 for about $5. The cups hold 8 oz. and came in clear plastic with red trim, red and yellow handles, and
a yellow tip; blue trim, blue and green handles and a green tip; or
purple trim, purple and aqua handles, and an aqua tip. The serial
number of the recalled cups is 382814, which appears on the back of the
packaging (like you kept the packaging, thanks for the handy tip, recall people!).
Take your cup back to CVS for a refund, or throw it away, I don't care which. But you're advised to stop using it either way.
