In order for me to ever send my kid here again (which I still wouldn't), I would make sure the center does the following: notify parents when an injury occurs so you don't have to wonder how/when/why it happened. Have happier teachers that do not act burnt out and miserable and have them stay home if they have a horrible illness. Talk to parents about behavior issues instead of separating the child from class. Do not ever tell the kid they belong in the baby room for their behavior. Take criticism when it is due.. don't pull out the ""you make me uncomfortable"" card if someone questions the actions within the daycare.
