Oh this age is so not my forte either ... I do agree with the sentiment that you can send off a perfect little 4 year old angel from your program to enter into school and what returns is some other entity you do not recognize ~ the attitude, the behaviors, they saucy playground mouth and so forth ~ they get exposed to so many different 'behaviors' at school that seem to work for other children and so they try to come back to daycare or the home in an effort to make sense of them by trying them all out on you or the daycare crew ~ it is exhausting!
