Advice, please. What would you do for a 4th birthday party being celebrated on Halloween at which one set of grandparents, 3 x 30-something parents and 4 children - sisters aged 6y and 4y7m; brothers aged 20 months and 4y1day - will be present? Grandfather is father of mother of girls. Grandmother is mother of mother of boys. (Grandparents married when their daughters were grown up.) Both mothers and boys' father will be there. Children get on well; we all do. I am grandmother. Because she and her family will be travelling back from a wedding all the previous day, and she will have to bake the cake on the day, my daughter asked me to be 'games mistress'. What would you do if you were me? I imagine I need to have activities to occupy about three hours, not including eating (an afternoon, in fact). And I shan't be in my own home, but my daughter's.
