An interesting phenomenon occurred with multi-pointing. I don't know when Juli began multipointing; that is, pointing to more than one image at once before looking at me for naming. But, I began to notice lately.
Early at 12 months, Juli pointed to 1) bicycle and 2) football. I simply dismissed multipointing, thinking that Juli just changed her mind. I uttered football. She pondered for a moment before vaguely pointing to the bicycle.
Then Juli pointed to the image of a basketball. I uttered it. This whole scene happened to be captured on video.
Two days later, Juli opened the same book and multipointed to 1) basketball, 2) football, and 3) bicycle. Her pointing was a clear intention for each of these items. I intuitively uttered all of them respectively.
Juli thought for a moment and pointed to the bicycle again. I thought she was double checking because this item was fairly new, while the other two had been somehow familiar to her.
This whole scene was captured on video and I didn't recall the previous event until I edited those videos and discovered this interesting link.
Likewise, Juli often opened another book, looked for the specific adjacent images or pages of the goose and the kitten, and pointed to the kitten and/or the goose.
One morning Juli pointed at both images of the kitten and the goose and looked at me. I simply uttered both at once.
With the similar incidents in two separate books, Juli seemed to explore the concept of multiple pointing and watched what happened.
