Yes, I agree. Most kids cry like this the first day or two (or for the first week for some). OP, you have to remember that this child has been home with mom exclusively picking her up and responding to every whimper for a whole year. The child has learned that crying gets her what she wants. It's not the child's fault. She just needs to relearn how it works at your house and in group care.
Just don't pick her up. Not at ALL. Seriously, you are teaching her that crying gets her a reward of being picked up. When she cries you take over a toy to her and offer it and tell her 'that's enough' and you walk away. It is very easy......desired behaviour gets positive results, undesirable behaviour gets NOTHING.
Ignore, Ignore, Ignore and she will be fine in a week.
