They are great. You wash them off after eating and they are dry by the next meal, no mold. You can throw them in the washing machine too. With my first I kept buying different bibs and when they got yucky I had to buy more. I bought 3 bumkins 18 months ago for my second and they still look like new.
Absolutely - fantastic product I found them on babycenter.com. I bought 2 sets and didn't need all 6 bibs because they never got stained, were just perfect, easy to wipe or wash. I gave up on all the cloth bibs after using these!
