If you are in the position to, take her out. Carers play too big a role in their development. We took DS out of a centre because things weren't what we thought they should be. The little things tell you a lot about their attitudes towards the kids. The center you are describing makes me uncomfortable and I wouldn't leave my child there. It sounds like there is also a discrepancy between the centre policies and reality (eg. the policy is you can stay the first day but the carer discourages it).
