Binkies with your kid's name on 'em!
You go through a pile of pacifiers every week. Your kid drops one at playgroup and have no idea which of the five pink germ-infested binkies belongs to your kid.
These pacifiers can be personalized with your kid's name so you'll never stick someone else's kid's binky into your kid's mouth again. They come in different colors (I like the glitter ones) and sizes for different age kids. There is also a line of "Expression" binkies with funny little phrases like "McDrooly" and "My Mom Rocks" on them. And at under five bucks a pop, they make really great, affordable baby gifts.
