teething biscuits are to babies as bones are to dogs
Now, to be clear I am not comparing my child to a dog but rather the purpose of the teething biscuit to a bone. To mildly amuse, sooth sore gums, and keep one occupied. The "biscuit" is pretty disgusting after being gnawed on for a few minutes and is a slippery little thing especially difficult for little fingers to grab which can result in some serious drama.
