I'm not sure from your post how long she was with each of these caregivers before she was "kicked out". Some children will do just fine when/if they can get comfortable with a caregiver, even if they are not getting constant attention. Even if you get one-on-one care, your daughter will still miss you and may not cry or fuss less often. If the caregiver in a group setting is kind and empathetic, rather than treating separation anxiety as a problem with your daughter, and your daughter is given enough time to be comofrtable with her caregiver, then she may bne just fine.
Chace started attending the Toddler Center here at UCSC about three weeks ago. He is there in the afternoons, 12:30-5:30. Even after three weeks, he cries ferociously when we leave him there. The center has a 3:1 ratio, with each teacher assigned as a primary caregiver to three children. He is really bonding to his primary caregiver, so even though he is very sad when we leave, he goes to her for comfort and reassurance. He usually starts to miss us again, and she helps him deal with his feelings without minimizing them or blaming him. He is just a very attached little boy, and he needs a little extra support to make the transition. It is getting better all the time, although Mondays are always rough.
I would recommend finding a caregiver, whether in-home or not, who understands the nature of attachment and separation anxiety. The caregiver should give her time to adjust and not decide it isn't working after a couple of weeks.
