DD has just started year 1. In the past year or so there have been 3 or 4 parties now that seemingly everyone is invited to and DD is not. All her closest friends have got invites but DD hasn't. Now I could just be a bit paranoid but I guess at their age the mummies have more say in who gets invited. So my paranoia is that I am not making enough of an effort with the other mummies. To be honest I keep it to cheery hellos, rather than full on chats in the playground, all the cliqueiness wears me out. Must I make more effort or should I just not get bothered about this in the first place!!??
