Tonight I had the rare chance to take just the twins to Trader Joes. I had carried Ruby around and played with her a bit in the morning, so while at Trader Joes I chose to carry Jack in the sling. Ruby got to ride in the cart (in a buggy bagg of corse!). All of a sudden Jack looks up and says “Momma Momma,” and signs light. I was thrilled that he recognized and signed it correctly so I clapped and cheered him on. Ruby, being the observant one, noticed the excitement and had to do it as well. She looked up and signed light as well all while looking up at the light. I swear she knew exactly what she was doing. She knew that the behavior would get a positive reaction, so she did it too. What a smart girl (and boy too!).
BTW, I cheered her on as well!
