2nd child I got gaslighted again until I went to the _specific person_ who had diagnosed it correctly the first time. And yeah, exactly the same problem (different symptoms, but children are different). Turns out she’d been disciplined after the first time for stepping out of lane.
(You’ll note, not for being wrong, the diagnosis got independently confirmed both times.)
Medical professionals like and are used to being the unquestioned experts. But you are always the expert of your own child (because, like I said before, every child is different.)
By the second child i was too tired to keep stats, so we winged it and the docs and I happily acknowledge that ignorance is bliss (sarcasm, i think).
