I agree PP, I don't think she's ready and I'd be pulling her out too - I think you've done the right thing.

She's still very young, my DD didn't start any type of care till she was 3 and she took to it like a duck to water, not a single tear from day one. I was very lucky but I think she was also very ready!

If you are interested in her socialising with other children a bit more, I'd suggest play group. We did this for about 12 months before DD started preschool. She loved it, I was there with her so it wasn't stressful for either of us, she got to play with other kids and it got us both out of the house.
