The sun hadn’t even risen yet, but my daughter, Rylae-Ann, was already melting down about changing out of her pajamas. By the time we got downstairs to start breakfast, her mood had only soured. By noon, everyone in the house had veins popping out of their heads…

During my teacher training, one concept stuck with me: the first critical period of brain development occurs very early in life, between ages 2 and 7. At the time, it felt like one of those powerful, slightly intimidating facts professors love to emphasize. You nod, write it…

As I straightened my tie in the mirror, I could hear my daughter’s giggles getting progressively louder as she stumbled her way to my bedroom. When I heard her finally enter, I glanced over my shoulder and was greeted with a delightful scene that looked like a pink baby elephant…
As I tried desperately to fall asleep after a long day, my daughter’s fingertips danced around my jawline. They explored over my eyebrows and across my lips. In the morning, her investigation resumed, finding my nostrils and pulling my eyelids open. My daughter, Rylae-Ann, is diagnosed with…
Our daughter, Rylae-Ann, failed to meet her milestones at 3 months old. From that point on, she was limp and barely moving. However, she was still very much full of life, and my wife, Judy, and I would help her to still experience the world. Even before we learned Rylae-Ann…
My wife, Judy, and I have attended webinars, conferences, and other events to share our perspective on our daughter’s experience with aromatic l-amino acid decarboxylase (AADC) deficiency. We have written letters, articles, and books advocating for research and treatment. Now, achieving our greatest…
My wife, Judy, and I have dedicated our professional lives to educating children. Books are an essential tool, but I never imagined that we would become authors. When our daughter, Rylae-Ann, was born in 2018, we surrounded her with books and read to her daily. However, when she was 3…
Our daughter, Rylae-Ann, quickly prepared a selection of delicious ice cream and scooped some onto a cone. She excitedly called out her friend’s name and passed him her colorful concoction while shouting a series of words to explain what she’d created. Rylae-Ann was born with a rare disease known as…
My “Journey of Beautiful Destinations” column is designed for caregivers. In each post, I consider the nuances and specific challenges faced by families who are affected by aromatic l-amino acid decarboxylase (AADC) deficiency. However, I also communicate with doctors and healthcare professionals to share insight with…
My daughter, Rylae-Ann, chucked her cup and its contents of sweet juice across the room. As the plastic cup bounced to a standstill, it took every ounce of patience not to respond with anger, but rather thoughtful, positive language. Rylae-Ann Poulin, 5, practices properly holding a cup and drinking…
Glow sticks danced in the air as I snapped pictures of us in our striped socks. The fun day was my family’s first event dedicated to rare disease awareness, but while it made for great photos, it wasn’t a day of action for us. We were still newbies at that…
Chinese New Year celebrations are a two-week extravaganza filled with food and excitement that can overwhelm the senses. Our daughter, Rylae-Ann, was born with aromatic l-amino acid decarboxylase (AADC) deficiency. This rare disease required my wife, Judy, and I to work as a team to keep our…
One minute, it was a slow coo, and the next, a high-pitched scream. It may have sounded obnoxious to a random observer, but for us, it was speech. It was a long way from where a typical 3-year-old should be, but it was an exciting milestone for us. Our daughter,…
