I will be visiting my sister in the Twickenham area next week with my two dds (4.5 and 2).We are hoping to get out and about a bit (we'll have use of her car). Can anybody recommend things to do with small children? It doesn't have to be anythings major like Thorpe Park or Legoland perhaps nice parks with play areas, farms, indoor play areas, museums aimed at younger children, activity days etc.
We will venture in to central London one day to meet friends at the natual history museum for a couple of hours. All suggestions welcome.
