People keep suggesting that I try these teething biscuit/cookie things with E since she's cut a tooth and is more actively teething and is eating some solids. I don't really relish the thought of having sticky cookie goo everywhere so I haven't tried them. Not sure if they are healthy or loaded with sugar? Does it depend on the brand? Any good brands? Can I make my own? Should I avoid these? She doesn't seem to care at this point about what she chews.
