we went to see two on friday, in the second one one boy had another in a head lock and was hitting him (they were about 2 years old), we left the room before i saw waht they did to sort out the situation. I wish i had asked now what their policy is to deal with situations like that.
Also take your Lo with you if you can, watch how the staff interact with them.
Check staff turnover rates.
food what do they serve and why
age range of classes, one we saw had age range of 0 to 18 months for their youngest, they second had 0 to 11 months and then 12 to 18 months.
those are the things that stood out to me.
