A mom took these adorable pictures of her 2-year-old daughter and her dog in identical poses

Then she took another. Today, the series of of juxtaposed images contains more than 100 images posted to her Instagram account.

Holland is a wedding photographer by trade, but has used this side project as a way to document her daughter's childhood beyond just iPhone captures (although some of the images in the series are actually taken on the iPhone).

"I love shooting weddings, but this has been a fun way to make my husband, family and friends smile, and most of them are much more interested in this series then wedding photos of people they have never met," Holland tells Business Insider.

Below are a selection of the photos and excerpts from our interview with Holland.
