Just off the back of another thread and out of curiosity... I hear a lot of people talking about cliques in the playground at school run time. Is this only a thing in larger primary schools? My DS's school is fairly small (one single class of around 30 per year group) which doesn't give enough scope for cliques to really form in my opinion as there aren't enough parents per year group, especially when you take into account quite a few parents work so alternate between Mum and dad who does the pick up/grandparent or childminder does the pick up.. it just means there aren't these armies of intimidating mums I seem to read about?
