when our daughter who is now 19 was only about 11 to 12 months old, and was just starting to walk around, (and touch everything), whenever she would reach for something at my Mothers house that she wasn't supposed to touch, I would say no, while shaking my head no, and if she didn't stop touching it, then I would go to her and give her hand a light tap on the back to make my point. This ALWAYS worked with our oldest child, however our oldest would just move on to the next item, and the next item, so it was a very busy time until we went through everything there was to "touch and say no to, but not with THIS child. One day, when I saw her reaching out to grab a hold of a very fragile nick nack on a shelf a Nana's I started to shake my head and say No, and at the same time was rising from my seat, assuming that a light touch on her hand may be needed, but before I could get totally upright she looked right at me started to shake her head no, and say no, all the while she kept touching the item. Then for some extra humor, she actually slapped the back of her own hand, saying No over and over, while she was still touching the thing on the shelf. (this went on for pretty much the next 2 to 3 months, so I had to find a new approach for my child and not wanting her to get into things) I had such a hard time keeping a straight face, it was so adorable!!
