Short of wrapping your baby in a garbage bag (or perhaps bagging up the entire high chair), it's hard to imagine a mealtime where the kid doesn't emerge covered in food. Bibs just can't keep them totally clean. And while it's true that even this hi-chair bib from Poi Wear probably won't leave them spotless, the longer design -- complete with split to fit around the high chair bar and cover the legs -- comes as close to practical full coverage as I've seen. $20 apiece for a variety of patterns.
