Yup - totally depends on the personality of the child in question, if they were 'prepared' for group care by their parents, how they were transitioned into the program either cold turkey or several short play dates with parents and than without before going the 'full day' sort of thing.

Typically in my experience it takes a couple weeks for them to get comfortable to be eating and sleeping normally and out of the crying A LOT during the day at every transition and so forth and about 2 months for me to get them to the stage where they NEVER cry anymore ... I have a new one whose been coming about 5 weeks now and he comes in happy now and reaches for me from his mom, he eats and drinks, he is sleeping better, he plays happy and moves through transitions better but good lord if I step out of his line of vision you would think someone pulled his toenails out ... he is not secure enough yet to trust that I too am coming BACK from the bathroom
