Mia was not quite up to feeding them yet, but they showed a lot of interest in the pushchair!
Then I was persuaded to buy Harry an icecream in the tearoom. There is a path all the way around the lake, although it's a bit rocky with the pushchairs so we only managed a short distance. From memory the path also joins up with some other longer walks across the Downs. There were some small hills that the boys could climb, and I even got Mia out of the pushchair for a crawl about, although it turned out that she was more interested in eating sticks.
Then as a bonus, both fell asleep in the car on the way home. If only all the fresh air meant that they would sleep better at night!
