I'm not sure if I'm repeating what someone else said, but the first thing that popped into my head was, suggesting they find a daycare where the caregiver speaks Chinese AND English that way Anna can be comforted in a language she understands and she'll be able to integrate easier that way. I would be freaked out too if I was surrounded with people I couldn't understand. Poor girl and poor you!!! I can see how that would be so stressful!! Good luck!!!
