My children both attend/ed blossoms Montessori for pre school, the days are 9-4 term time only and it is encouraged to take two consecutive days at least. My daughter will increase to 3 days in sept in preparation for school, but they were fantastic with my son and suited us really well both children had/have a fab time there and they go, in my opinion, above and beyond what is expected for preschool, but it is all done in a very child centred way.
