If I remember rightly, the nursery which was attached to the infants school where mine went, took the children on a basis of starting the term that followed their 3rd birthday, although if that was a late summer birthday, they started after Christmas and not in the September. Prior to that mine did a couple of mornings a week in a kindergarten from aged about 2 and 3/4. My younger one met his best early years friend there bonding over Thomas the Tank. His mother and I were delighted to know that they were going into the same school nursery and school thereafter. I think it depends on the child as to when they start. Some children have separation issues at the outset, mine did initially, which they got over. Having said that I had two friends with August born boys who felt they went into the system too early. Mothers are the best judge as to when their child is ready, go with your instincts.
