Apologies for weird title.
My Dd is 8. She has an unusual memory she can recall dates/days of the week/times of specific events. Not everything but a lot.
For example I was talking about a random play date we did with family friends a couple of years ago and Dd then said yes I remember that day it was 27th a Tuesday wasn’t it. I went back to calendar from that year and she was correct.
This has happened numerous times with non important events that Dd can remember precise details on.
She was able from 2 upwards to memorise routes, where things were in which shops (she could recall which aisle etc)
Dd is performing well at school and really good at math (far better than me now and she’s 8) could it be she has a mathematical brain if that makes sense?
Teachers have never commented just that she is excelling in her subjects.
