If she was 5 before July you could think about it, but since she won't be 5 til the end of the year wait.
The guide lines are if they turn 5 before July 31, or 6 after.
DD was 4 til April last year in Kinder.
DD2 will be 5 in June, so I'll have to wait & see how she is before I send her. See if she's ready.
Its up to the child, but I think she's too young yet.
