We have been v.happy with Eveline, the staff turnover is low & they have chosen to be nursery nurses, many of them have done NVQs. The staff are so kind & affectionate with the children & you feel as though they really care & not just because it's their job.
Apparently Wee Ones is not a "proper" montessori, that was why our friends moved their child & I don't think they are that flexible on days.
Eveline don't do half days but do offer flexibility as to which days you have. Fridays are a much quieter day for them so that might be a good day to go for if you only want one day a week?
PM me if you have any more questions
