I defended my kid to a relative and now there's tension
ADHD parent behaviour
Advocating for your child against family pressure means tolerating disapproval, which is exactly what ADHD rejection sensitivity makes hardest, so the second-guessing is your RSD talking, not your judgement. You drew the boundary despite the pain, and that is strength. Do not retract it. You can soften the delivery later, but the position holds; your child's needs are not negotiable because a relative is uncomfortable.
What to do right now
You drew a boundary for your child and now the room is tense. The relative is offended. You are second-guessing. Do not retract. The boundary was correct. You can soften the delivery later if needed, but the position holds. Your child saw you stand up for them. That matters more than the temporary tension.
What your brain just did
Your body
The tension in the room is your nervous system processing the social cost of standing up for your child. The second-guessing is your rejection sensitivity, not your judgment.
Your brain
Advocating for your child against family pressure requires tolerating disapproval, which is exactly what ADHD rejection sensitivity makes hardest. You drew the boundary despite the pain. That is strength, not conflict.
What this did
The boundary holds. You can soften the delivery later if needed. But the position does not change. Your child's needs are not negotiable because a relative is uncomfortable.
