my 8 yr old daughter crys all the time when going to school etc she says she doesnt know why she enjoys school has friends likes her teacher and is a good pupil.i have tried sitting her down and asking her why she is getting upset she just looks at me blankly and starts welling up.I have tried ignoring it,she cant give me a reason and there doesnt seem to be one,she can be doing something she wants to do at the park say and can just start crying.
