When we were ready to potty train our two year, I purchased this book box to be his special potty books. Boy, did it ever work well! He loved to sit on the potty and read his special train books. The best part, is that Mom and Dad liked reading them, too (I'm partial to the Crack in the Track). Once potty training was a success, the book box travels with us in the truck and our son is "reading" using the picture clues and knowledge of the storyline. Our little guy just loves having a special box for his train books. The handle has held up well, and considering the amount of use, the box itself has, too. The front flap, however, is starting to wear from opening and closing (probably because of the strength of the Velcro). We'll buy this set again for nieces and nephews!
