My 4.5 yo has friend over. She wont stop playing schools (my child that is) & is totally in character as bossy & patronising school mam, the other child is utterly bored & bemused & keeps walking off but mine bosses her back. Any attempts I've made to encourage other games have resulted in huge tantrums from my girl..& I am quite suressaid friend won't ever want to return..what can I do?!
