Mill Hill pre-prep schools

[sokaribo]

Hello, I'm new to this website and job board and was wondering if anyone has any young children at St Martin's, The Mount or Grimsdell (Mill Hill Foundation) school and what your views of the schools are?
My daughter has been offered a place to start in their nurseries in Sept this year and despite visitng the schools, I have some reservations about each of them.

The pro's and con's for us so far are: We like St Martin's as it seem's quite nurturing and it will also enable us to send our son there in 2015. But, the school seems very small and clustered.
The pro's for The Mount is that it's on our doorstep, it offers full days plus after school clubs from 3 years which will help when I go back to work. The downside is that I have a 1 year old who would then need to attend a different school,I would have ideally liked them to be together.
Grimsdell has offered us a place for afternoons only this Sept. The school prospectus seems impressive and I like the facilities it offers. Again, the days in nursery seem quite limited.

Sorry to drag on but I really would like to hear your views on the schools. Many Thanks
