I do remember my mother reading to me in bed as a little child some 55-56 years ago.
I also remember her teaching me, so I guess I would have started before school.
Not sure if I liked it, because I also remember it didn't always make me happy.
I still did it, and I know got a lot better...lol.
Probably about 4. Iwas able to read when I went into Grade 1 & I was 5y2mths of age. Had to wait til I turned 5, to go to School, as in January School start time, i would've been 4y10mths old.
I loved Reading, still do, & always got ten out of ten for it in exams! Lol!
It went hand-in-hand with ENGLISH Subject & Elocution, the latter starting in Grade II, wasn't allowed to start any earlier, although I wanted!
