We've used 3 nurseries for 3 children.
The first nursery was "outstanding" according to OFSTED, sounded fabulous on paper, had to book a visit to look around, all lovely, very clean, lots of new equipment, almost "posh" ifswim. Signed children up. When they started (twins) it used to niggle me that they were always referred to as "they" - never "he's enjoyed X" and "She's enjoyed y". They were seemingly happy there but the lack of feedback / communication was an issue for me, as was the fact that we dropped off / collected them in a large hallway, never seeing what went on in the classrooms. The staff were nice enough, but mostly 18/19/20 yr olds, early 20s, seemingly high staff turnover. So I started looking for other nurseries..
Went on a waiting list for Nursery 2 and got places 10 months later. When I told the manager at nursery 1 that we were leaving, she asked why and I said because there were a couple of things that I'd been unhappy about. I asked her if she wanted to discuss them and she said no, she'd been a parent of 3 for the best part of 20 years and there was nothing I could tell her about looking after children. ....That confirmed it!!
Nursery 2 couldn't have been more different. Still clean but a bit tatty round the edges, but chatty staff with genuine interest in the children, loved feeding back what they'd been doing all day, were cuddling the children most times when I collected, they just really seemed to love them. Children were there until they started school (2 yrs). Never questionned my decision.
Moved areas by time Number 3 was born so needed another nursery. This is fabulous. DD2 runs in, absolutely loves it, most recent member of staff joined about 10yrs ago. The issue with this one is avoiding the owner
if you end up in a conversation with her, you'll still be there 20 minutes later!! She knows every single child, what they do, what their favourite activities are. Very hands on. Mountains of feedback - verbal, newsletters, emails, regular updates, one to ones and always notification if the staff are moving rooms.
I would say you have to listen to your instincts - I think if you are unhappy with the nursery then you should change. I don't think price has anything to do with it - Nursery 2 was cheaper than Nursery 1, they shouldn't be provided "better care" just because the fees are higher. Yes, they might have more facilities or a couple more members of staff, but the standard of care should be the same.
