When our first child was born we had plants in the living room. He loved to touch them, but for obvious reasons, we didn’t want him to. So my husband and I would say, “No. No touch.” when he would touch them. We were wondering if he was understanding the boundary we were instilling. Then one day it became clear. At age one, having just learned how to walk we watched him slowly move backward towards the plants. He kept looking around the room as if to communicate, “Nothing to see here.” After backing up to the plants, still looking away from them, he reached out the back of his hand to brush across them over and over. We started laughing, while thinking, “You are a sneaky little guy!”
