This VTech Baby Caterpillar makes a great teething buddy! The Two soft and chewable teethers help sooth tender gums. Put the purified water-filled apple shaped teether in the fridge to cool it down and make it even better! Turn the lock on the back to remove the teethers to give them a clean. There`s also a light-up button that plays three sing-along songs, 10 melodies and fun spoken phrases!
