When the children were small we occasionally did slightly crazy things – like eating a meal in a bizarre place e.g. on the floor under the dining table. This ruse came in really handy when a proposed trip out had to be postponed because of pouring rain. Stuck inside the house, toys ceased to engage interest and children needed a change of some sort, to rediscover their enthusiasm. In those days I could easily slip under the table and lay out a table cloth, cutlery etc and serve a picnic on the floor. I’m a bit stiffer these days – but I guess that I could still manage to improvise if need be. How about sitting on the stairs, or a picnic basket + blanket in the loft?
Or breakfast in the garage?
