This probably has come up before, but have you considered Family Daycare instead? She may be more suited to it. Also you might be able to do 2 half days, which might be easier on her.

I remember it taking a while for DD1 to get used to care and I was just using occasional care at about 9 months so I could go to appointments. What helped was having her babysat by a friend who I visited a lot, so she was used to the person and the place. She still got upset, but it helped to ease her into time away from me. Once she got better at that she was able to do a short day (9-3.30) at childcare when she turned 1. Also by that time DH had been having her by himself for 3-4 hours, even with him she still missed me. Now at 3 she asks to go to childcare, but that could be due to me being a bit of a grumpy bum at the moment
