I bought these for a week long vacation with my 15 month old. I thought they were very cute and worked well, but there are a few challenges. First, there are dot stickers in the back of the book that you use to hold the bib together. The problem is that if you don't want to take the entire book (which is big) and tear off a couple to throw in your diaper bag, you have to stick the stickers onto the bib which makes it lose some of its "stick" when you go to use it. In addition, when you fold it up to put in the diaper bag, it creases making it not lay flat against the chest. My little girl also kept pulling them off, so I ended up not using them. I'll try again when she's a bit older as they may work better then, but for now will stick with bringing a washable bib, like a Babybjorn one, when I vacation.
