I have my ds name down at Little Sparrows, the Montessori in Imber Court, and River Mole Preschool in Esher. Does anyone have any experience of any of these? And how good are they are preparing for school i.e. a bit of writing etc, which the primaries seem to expect these days. Also have considered using 15 hours towards private as i'm sure it would be a great start, but could it be too formal a setting at age 3, esp when they will be in school and school uniforms for next 15 years!?
