Rattlers are pretty basic, in that they make noise to get a baby's attention. But the SmartNoggin NogginStik goes a step further: It also lights up, which could help to snap your kid out of an epic freak-out session. It has a goofy face, something that helps little ones learn to recognize human faces. And it also has a ridged handle, which encourages motor development, as well as a mirror on the bottom. That variety means there's less of a chance your baby will get bored with it, and makes it essential for every diaper bag.
