Immediately after saying these words, Kate’s voiceover begins, where she shares that “As the summer comes to an end, I cannot tell you what a relief it is to have finally completed my chemotherapy treatment,” she said.

“The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant, and we have had to find a way to navigate the stormy waters and road unknown.”

At the start of the video, Louis walks ahead of his parents and two siblings, throwing a ball as they venture through the woods.

Later on in the video, Louis can be seen being pushed by his mom on a swing, and viewers can even hear his voice in the clip as he leans into the camera and says, “Hello, hello.”

“Pop that in the fire, Lou Bug,” Kate could be heard saying as she told her youngest to discard a stick in the fire.

That same day, Louis shoveled sand into a wheelbarrow and pushed the wheelbarrow over to other volunteers as his mom stood close by, encouraging him.

“Well done, good job Lou Bug,” Kate said to Louis, who had just turned 5 at the time.
