Leucovorin Update – Week 10 (7 weeks at goal dose)
We are now at week 10 on leucovorin, with approximately 7 weeks at her full dose. We continue to see meaningful changes, particularly in expressive language, singing, and spontaneous social interaction. She is now also within or ahead of all of her milestones.
Singing has become a major area of growth. She now sings along anytime music is present, whether live or on TV, and is able to accurately mimic the tune. She will also sing strings of words from songs she has heard from memory, while carrying the tune. In addition to this, she is spontaneously making up her own songs throughout the day with original melodies. In this video, the song is mostly nonsense, but it is clearly centered around her sister (“Ro ro”), which feels significant in terms of social referencing and intent.
Her speech clarity has also improved. She has been intentionally practicing consonants (e.g., “la la la”) and working on annunciation, and as a result, most of what she says is now intelligible. Previously, she was attempting many new words that were difficult to distinguish, and this shift has been noticeable. She has also begun playfully copying what we say to tease us, which reflects growing social awareness and receptive–expressive language integration.
In addition to language gains, she is showing more creative, spontaneous, and expressive social behaviors. She will sneak up on us and say “boo,” approach us to give unsolicited kisses, put on accessories and show us, and ask us to put her princess dress on her and then spin. She will also stand in front of the gecko enclosure, point then clasp her hands together, and exclaim “aww.” These interactions are unprompted and consistently directed toward shared attention and connection.
Overall, it feels like she is not just acquiring new skills in receptive language comprehension, expressive output, and social-emotional awareness, but becoming more intentional, expressive, and socially engaged, with increased initiation of play, affection, and shared enjoyment. These changes have occurred while maintaining her goal dose of leucovorin and continue to be very encouraging.
