Chew on this.
This bite-proof sippy has an ultra-durable yet soft spout that won't tear when it meets even the most tenacious of teethers.

Our new Click Lock™ sippy cups come with a soft, bite-proof spout and a 100% leak-proof guarantee! These innovative cups feature a simple locking lid that closes to create a leak-proof seal. You can see, hear and feel the cup lock in place, so you have triple assurance against dribbles and drips. We even back this no-leak promise with a 100% replacement guarantee. Secured, and rest assured - this might just be the sippy cup of your dreams.
