Both my children attended the Montessori in Balham (my younger son is about to leave at the end of this term

). My older son started at the nursery in 2010 and I cannot say I have had one bad experience in the last 6 years! It is an absolutely wonderful nursery - the staff are amazing and they have very few staff changes. They are extremely warm and caring and they have gently encouraged both my children in areas of becoming more independent and develop their numeracy and literacy skills. They teach the children in small groups (groups of 4 or 5 when they first start) and although they don't have much outdoor space they still do physical activity in form of gym and ballet. I cannot recommend it highly enough. Sounds like if you have places at both nurseries you won't be disappointed by either. Good luck making a decision and please PM me if you need any further info.
