I have a good friend who's PFB (lets say Max) has just started the same preschool that my DS2 goes to (and DS1 went to). She tried for many years to have him and he is a very wanted child.
Every morning she makes such a song and dance about leaving Max - 'Max I am going now'. 'Max will you be okay?' 'Max will you miss Mummy?' 'Dont worry Max, Mummy will be back soon' this goes on for a good 15 minutes. Max is absolutely fine and is off through the door without a second glance, but she is starting to look a bit like a loon, plus he might start playing on her need to be needed. She is a lovely lady and the kind of person that wouldnt mind being told, but would you?
