Any parent reading this rubish should be OUTRAGED that Amazon would even consider selling this book! This is plain outright CHILD ABUSE 101! I cannot imagine ever HITTING a little one to teach them..teach them what, that you are bigger than they are at 18 months? If we as parents cannot do a better job or disciplining our children than hitting them, we don't deserve to be parents in the first place.AMAZON, QUIT SELLING THIS BOOK!
