hi, I'm a mom of 5 yr old pre schooler. He likes going to school like any other child. He will enthusiastically get ready and walk happily on his way to school. But as we reach his school he insists that I stay there with him. 2 weeks back he used to say goodbye to me like any other kid. But now he insists that I stay and when I leave will cry for a little while. Any ideas on how should I approach this?. Also when I ask his reason he just says that I stay.
