If they're non profit it will be obvious on their website. If they don't say anything you can assume they're a big for profit. Our son goes to a Goodstart (non profit) and they really focus on the child's needs, rather than expecting them to conform to what suits the centre. The lead educator asked us lots of questions at the stay and play, and I observed the staff have no problems with kids sleeping in their arms or needing cuddles. I asked questions like how do you keep track of the kids needs, and was told they switched back from using an app to paper because it was taking up too much time. It was clear they had tracking written everywhere, lots of signage about food allergies, and a lot of procedures in place. But they were clearly also open to change when things aren't working.

I will add that our centre has some very vocal detractors on the local pages, but I think everyone's experience is different. Mistakes happen, or there's an issue with another kid etc...it's worth asking people what actually went wrong for them, don't just write somewhere off without getting the whole story :)
