DuellingFanjo, you must feel good about your DC going to their nursery otherwise surely you would find another one - its probably delightful isn't it?!
Bad ones: smelt of wee, lots of kids with raging nappy rash, kids not engaged, left to cry endlessly, broken safety gates, staff spending hours doing paperwork rather than playing with children, lying to parents 'oh he's had a great day', no hand washing, all children with colds constantly, no nose wiping, germs everywhere, toys dirty, staff attitude to children less than loving, fake or small outdoor space, babies with bottles propped up by pillows instead of being held
delightful ones: clean, fresh, staff dedicated, teamwork, lots of cuddles, story reading at any time, constant attention/supervision from staff even if just watching them learn or develop on their own, not as much paperwork (largely independent nurseries rather than chains), healthy food, nice outdoor space - actual grass for eg, some of the churchey ones were truly iddylic with oldy woldy staff who had worked there forever and new the whole family type thing... some had full on adventure playgrounds outside with playgrounds and trees and sandpits which were delightful, toys cleaned regularly, noses wiped, poos changed immediately
so lots of this you would probably be able to tell yourself but like i said, i got it wrong a few times
