My LG is 2.9 (3 in April) and has recently moved up to pre-school with the 3-4 year olds as the nursery class thought she was ready.
She only started yesterday so as I expected has been getting upset about going in which I find heartbreaking and am starting to worry she's gone too soon. However, it is still such early days so I'm wondering what age your LO was when they started pre-school and how long it took them to settle in?
