**Leucovorin Journey Update – Week 14 (11 Weeks at Goal Dose)**
For those who are new here, a little backstory 💚
Our daughter experienced a significant mold exposure early in life that triggered a systemic immune response. What followed were cascading food sensitivities, gut inflammation, and nervous system dysregulation. After we had made meaningful progress, at 14 months a second exposure occurred — and that’s when we saw a regression in behavior and a stall in expressive verbal development (she had only just started speaking, and was basically nonverbal but would occasionally say 'mama', 'dada' or 'that').
As both a mom and a practitioner, it was heartbreaking and clarifying all at once. We knew her brain was capable. We had seen her light. But something was blocking access.
Fast forward to today. We are now at **Week 14 of leucovorin therapy, 11 weeks at her goal dose.**
And the changes continue to humble us.
At 23 months old now, she is not just “catching up.” She is exceeding milestones. Her vocabulary is expanding more rapidly each week. She is independently forming 2- and 3-word sentences to express herself and ask for what she needs — often including descriptors like colors. (“Blue cup please.” “Big sister help.”)
She seeks out interaction at the playground. She initiates play. She laughs easily. She is deeply protective of both her older and younger sisters.
And she sings. All. The. Time.
But what moves me the most is something harder to quantify:
Her eyes.
They have not looked this calm, clear, and present since she was just a few weeks old. The nervous system settling. The inflammation quieting. The connection restored.
We got our Riven Bear back. 🐻🤍
For those walking similar paths — whether mold, immune dysregulation, regression, or unexplained developmental shifts — there is hope. Healing is layered. It is rarely linear. But when you address root causes, the body remembers how to come back online.
Grateful. In awe. And continuing forward.
