(upbeat music) - Hi, my name is Julie.

My husband Adam and I have a six-year-old named Jack.

I have had multiple sclerosis, also known as MS, for 16 years now.

I always wanted to document things that I might not remember because of cognitive impairment.

From when he was born, I started writing him letters just so he would know how I felt.

I have a shared document with his father, and we can both jot our notes down, whether it be about his heritage, his first word, or if he lost a tooth, and just all these moments that you don't want to forget.

Jack, this is my favorite thing I've ever gotten.

I thought I would do that maybe for the first year of his life, and then I would print it out and bind it for him to open in, like, a time capsule.

The letters eventually turned into a book.

I started with letters, but we also do photos and videos just to capture those really important moments.

Every morning, Jack and I look at photos, and we just talk about how he felt on those days, and it's fun.

It's great to be able to look back and relive moments that were so special.
