Hi! I would recommend Little Bunnies on Wayneflete Street in St Andrew's Church Hall. It is not really plush looking like some of the far more expensive nurseries. However my son went there and loved it. He is seven now so it was a few years ago but I am pretty sure it is under the same management - there are two ladies who worked together in childcare for years and then set up together. The other staff mostly stayed long term as well. They were all really friendly and really cared about the children. My son went to three nurseries in total due to the first one closing and then we moved, and I felt very bad about him moving again but he really liked Little Bunnies and it was easily the best of the three. Because it is small, the children can get to know each other well. We looked at Buffer Bear as well and I thought that seemed lovely but I just preferred the more intimate setting of Little Bunnies - plus it saved me £300 a month
Good luck in your search - personally I would suggest visiting every nursery you can find and just getting the feel of them.
