if the child is right handed the hand they write with is right, see write--- right and the other hand is the left one. children are able to learn time at about 4 years and over, the o clocks are the easiest to learn.
I could read and write by the age of two years and could tell left and right and the time. So I suppose it is down to the indivdual child. Apparently I showed an avid interest in books and words and numbers when I was about a year old and my Mum just encouraged me and showed me when I asked, which apparently, was frequently. Poor woman was probably harassed like mad!! Still, it has given me a pasion for words and reading which I have never lost.
