Just feeling interested in other people's experiences, as it seems things may have been different from today when many of us started school.
I started school in 1980 when I was almost 5, as my birthday is in September. Full time from the start, although you had to go home for lunch for the first week. Children born from September to the end of February started in September, the others started in January. I do remember there being a few children from the year above in my class when I started - not sure when they went up into their "proper" class. Probably after Christmas.
